Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual portfolio operating expenses or in the example, affect the Portfolio's performance. During the Portfolio's most recent fiscal year ended December 31, the Portfolio's portfolio turnover rate was 37% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The following example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The table does not include Contract charges. Because Contract charges are not included, the total fees and expenses that you will incur will be higher than the fees and expenses set forth in the example. See your Contract prospectus for more information about Contract charges. The example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	In pursuing its investment objective, the Portfolio normally invests at least 80% of its assets (net assets plus any borrowings made for investment purposes) in medium to lower rated debt investments. Lower rated debt investments, in which the Portfolio typically invests, are often referred to as high yield bonds or “junk bonds” and are riskier than higher rated bonds. Lower rated and comparable unrated investments tend to offer better yields than higher rated investments with the same maturities because the issuer’s financial condition may not have been as strong as that of higher rated issuers. The Portfolio may also invest up to 30% of its total assets in US dollar-denominated securities of foreign issuers. Changes in the perception of the creditworthiness of the issuers of lower rated investments tend to occur more frequently and in a more pronounced manner than for issuers of higher rated investments. The Portfolio may invest up to 15% of its total assets in securities and instruments that are economically tied to emerging market countries. The Portfolio may invest in a security based upon the expected total return rather than the yield of such security. The Portfolio may also invest up to 20% of its total assets in collateralized debt obligations, including collateralized loan obligations, and other credit-related asset backed securities. The Portfolio may enter into short sales against-the-box. No more than 25% of the Portfolio’s net assets may be used as collateral or segregated for purposes of securing a short sale obligation. The Portfolio may invest up to 30% of its assets in reverse repurchase agreements and dollar rolls. In managing the Portfolio’s assets, the Portfolio’s subadviser, PGIM Fixed Income, uses a combination of top-down economic analysis and bottom-up research in conjunction with proprietary quantitative models and risk management systems. In the top-down economic analysis, the subadviser develops views on economic, policy and market trends. In its bottom-up research, the subadviser develops an internal rating and outlook on issuers. The rating and outlook are determined based on a thorough review of the financial health and trends of the issuer. The subadviser may also consider investment factors such as expected total return, yield, spread, and potential for price appreciation as well as credit quality, maturity and risk.

If Contract charges were included, the returns shown would have been lower than those shown. Consult your Contract prospectus for information about Contract charges.Annual return information in the bar chart is provided only for Class I shares. Because all of the Portfolio’s shares are invested in the same portfolio of securities, annual returns for Class III shares would be lower because Class III shares do not have the same expenses as Class I shares.

PSF PGIM High Yield Bond Portfolio | Risk Lose Money [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	The relative significance of the risks summarized below may change over time. All investments have risks to some degree, and it is possible that you could lose money by investing in the Portfolio.
PSF PGIM High Yield Bond Portfolio | Risk Not Insured Depository Institution [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	An investment in the Portfolio is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
PSF PGIM High Yield Bond Portfolio | Fixed Income Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Fixed Income Securities Risk. Investment in fixed income securities involves a variety of risks, including that: an issuer or guarantor of a security will be unable or unwilling to pay obligations when due; due to decreases in liquidity, the Portfolio may be unable to sell its securities holdings within a reasonable time at the price it values the security or at any price; and the Portfolio’s investment may decrease in value when interest rates rise. Volatility in interest rates and in fixed income markets may increase the risk that the Portfolio’s investment in fixed income securities will go down in value. In recent years, the Federal Open Market Committee (FOMC) began implementing increases to the federal funds interest rate and there may be further rate increases. To the extent rates increase substantially and/or rapidly, a Portfolio with significant investment in fixed income investments may be subject to significant losses. Changes in interest rates may also affect the liquidity of the Portfolio’s investments in fixed income securities.
PSF PGIM High Yield Bond Portfolio | High Yield Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	High Yield Risk. Investments in fixed income instruments rated below investment grade and unrated instruments of similar credit quality (i.e., “high yield securities” or “junk bonds”) may be more sensitive to interest rate, credit, call, and liquidity risks than investments in investment grade securities, and have predominantly speculative characteristics. An economic downturn generally leads to a higher non-payment rate, and a high yield investment may lose significant value before a default occurs.
PSF PGIM High Yield Bond Portfolio | Foreign Investment Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Foreign Investment Risk. Foreign markets tend to be more volatile than US markets and are generally not subject to regulatory requirements comparable to those in the US. Foreign securities include investments in securities of foreign issuers denominated in foreign currencies, as well as securities of foreign issuers denominated in US dollars and American Depositary Receipts. Foreign investment risk includes the risk that: changes in currency exchange rates may affect the value of foreign securities held by the Portfolio; foreign markets generally are more volatile than, and generally are not subject to regulatory requirements comparable to, US markets; foreign financial reporting and tax standards usually differ from those in the US; foreign exchanges are often less liquid than US markets; political or social developments may adversely affect the value of foreign securities; foreign holdings may be subject to special taxation and limitations on repatriating investment proceeds; and certain events in foreign markets may adversely affect foreign and domestic issuers, including, among others, military conflict, geopolitical developments, interruptions in the global supply chain, natural disasters, and outbreaks of infectious diseases.
PSF PGIM High Yield Bond Portfolio | Equity And Equity Related Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Equity and Equity-Related Securities Risk. From time to time, the Portfolio may purchase or hold equity or equity-related securities incidental to the purchase or ownership of fixed income instruments or in connection with a reorganization of a borrower. These include common stock, preferred stock or securities that may be converted into or exchanged for common stock—known as convertible securities—like rights and warrants. The value of a particular equity or equity-related security held by a Portfolio could fluctuate, perhaps greatly, in response to a number of factors, such as changes in the issuer’s financial condition, changes in interest rates, or heightened levels of inflation. Such events may result in losses to the Portfolio. In addition, due to decreases in liquidity, the Portfolio may be unable to sell its securities holdings within a reasonable time at the price it values the security or at any price.
PSF PGIM High Yield Bond Portfolio | Collateralized Debt Obligations Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Collateralized Debt Obligations (CDO) Risk: The risks of an investment in a CDO, which can include collateralized loan obligations (CLOs), depend largely on the quality and type of the collateral and the tranche of the CDO in which the Portfolio invests. Investments in CDOs may be illiquid. In addition to the risks associated with debt instruments (e.g., interest rate risk and credit risk), CDOs carry additional risks including, but not limited to: (i) the possibility that distributions from collateral will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the possibility that the Portfolio may invest in CDOs that are subordinate to other classes of the issuer’s securities; and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.
PSF PGIM High Yield Bond Portfolio | Credit Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Credit Risk. This is the risk that the issuer, the guarantor, or the insurer of a fixed income security, the counterparty to an investment or derivatives contract, or obligor of an obligation underlying an asset-backed security may be unable or unwilling to make timely principal and interest payments or to otherwise honor its obligations. Litigation, legislation or other political events, business or economic conditions, or the bankruptcy of the issuer could have a significant effect on an issuer’s or obligor’s ability to make payments of principal and/or interest. The lower the credit quality of a bond, the more sensitive it is to credit risk, and the credit quality of an investment can deteriorate rapidly.
PSF PGIM High Yield Bond Portfolio | Currency Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Currency Risk. Currency risk is the risk that fluctuations in exchange rates will adversely affect the market value of a Portfolio’s investments, including the risk that the currencies in which the Portfolio’s investments are traded or in which the Portfolio receives income will decline in value relative to the US dollar. The overall impact on a Portfolio’s holdings can be significant, and long-lasting, depending on the currencies represented in the portfolio and how each foreign currency appreciates or depreciates in relation to the US dollar and whether currency positions are hedged. Further, since exchange rate movements are volatile, a Portfolio’s attempt at hedging could be unsuccessful, and it is not possible to effectively hedge the currency risks of many emerging market countries.
PSF PGIM High Yield Bond Portfolio | Derivatives Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Derivatives Risk. A derivative is a financial contract, the value of which depends upon, or is derived from, the value of one or more underlying investments, such as an asset, reference rate, or index. The use of derivatives is a highly specialized activity that involves a variety of risks in addition to and greater than those associated with investing directly in securities, including the risk that: the party on the other side of a derivative transaction will be unable to honor its financial obligation; leverage created by investing in derivatives may result in losses to the Portfolio; derivatives may be difficult or impossible for the Portfolio to buy or sell at an opportune time or price, and may be difficult to terminate or otherwise offset; derivatives used for hedging may reduce or magnify losses but also may reduce or eliminate gains; the price of derivatives may be more volatile than the prices of traditional equity and debt securities; and changes in a derivative’s value may not correlate perfectly with the assets, rates, indices or instruments it is designed to hedge or closely track. The Portfolio is subject to a derivatives risk management program, which may limit the ability of the Portfolio to invest in derivatives.
PSF PGIM High Yield Bond Portfolio | Dollar Roll Transactions Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Dollar Roll Transactions Risk: Dollar rolls involve the sale by a Portfolio of a security for delivery in the current month with a promise to repurchase from the buyer a substantially similar—but not necessarily the same—security at a set price and date in the future. In a dollar roll, the Portfolio takes the risk that: (i) the market price of the mortgage-backed securities will drop below their future repurchase price; (ii) the securities that it repurchases at a later date will have less favorable market characteristics; (iii) the other party to the agreement will not be able to perform; (iv) the roll adds leverage to the Portfolio; and (v) the roll increases the Portfolio’s sensitivity to interest rate changes. In addition, investments in dollar rolls may increase the portfolio turnover rate of the Portfolio.
PSF PGIM High Yield Bond Portfolio | Emerging Markets Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Emerging Markets Risk. The risks of non-US investments are greater for investments in or exposed to emerging markets. Emerging market countries typically have economic, political, and social systems that are less developed, and can be expected to be less stable, than those of more developed countries. As a result, there could be less information available about issuers in emerging market countries, which could negatively affect the ability of the manager or a Portfolio's subadviser(s) to evaluate local companies or their potential impact on a Portfolio's performance. Characteristics of emerging market economies can include heavy economic dependence on international aid, agriculture or exports (particularly commodities), undeveloped or overburdened infrastructures and legal systems, vulnerability to natural disasters, significant and unpredictable government intervention in markets or the economy, volatile currency exchange rates, currency devaluations, runaway inflation, business practices that depart from norms for developed countries, and generally less liquid markets. For example, the economies of such countries can be subject to currency devaluations and rapid and unpredictable (and in some cases, extremely high) rates of inflation or deflation. Low trading volumes may result in a lack of liquidity, price volatility, and valuation difficulties. Regulatory regimes outside of the US may not require or enforce corporate governance standards comparable to that of the US, which may result in less protections for investors in such issuers and make such issuers more susceptible to actions not in the best interest of the issuer or its investors. Emerging market countries may have policies that restrict investments by foreign investors, or that prevent foreign investors from withdrawing their money at will, which may make it difficult for a Portfolio to invest in such countries or increase the administrative costs of such investments. Countries with emerging markets can be found in regions including, but not limited to, Asia, Latin America, the Middle East, Southern Europe, Eastern Europe, Africa and the region comprising the former Soviet Union. A Portfolio may invest in some emerging markets through trading structures or protocols that subject it to risks such as those associated with decreased liquidity, custody of assets, different settlement and clearance procedures, and asserting legal title under a developing legal and regulatory regime to a greater degree than in developed markets or even in other emerging markets.
PSF PGIM High Yield Bond Portfolio | Expense Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Expense Risk. The actual cost of investing in the Portfolio may be higher than the expenses shown in the “Annual Portfolio Operating Expenses” table above for a variety of reasons, including, for example, if the Portfolio’s average net assets decrease.
PSF PGIM High Yield Bond Portfolio | Interest Rate Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Interest Rate Risk. The value of your investment may go down when interest rates rise. A rise in interest rates tends to have a greater impact on the prices of longer term or duration securities. When interest rates fall, the issuers of debt obligations may prepay principal more quickly than expected, and the Portfolio may be required to reinvest the proceeds at a lower interest rate. This is referred to as “prepayment risk.” When interest rates rise, debt obligations may be repaid more slowly than expected, and the value of the Portfolio's holdings may fall sharply. This is referred to as “extension risk.” As interest rates rise, the value of fixed income investments typically decreases and there is risk that rates across the financial system also may rise. To the extent rates increase substantially and/or rapidly, a Portfolio with significant investment in fixed income investments may be subject to significant losses. The Portfolio may lose money if short-term or long-term interest rates rise sharply or in a manner not anticipated by the subadviser. Decreases in interest rates create the potential for a decrease in income earned by a Portfolio. During periods of very low or negative interest rates, the Portfolio may be unable to maintain positive returns. Changing interest rates may have unpredictable effects on markets, may result in heightened market volatility and may detract from Portfolio performance.
PSF PGIM High Yield Bond Portfolio | Leverage Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Leverage Risk. Borrowings, certain derivatives and other trading strategies can create leverage (i.e., a Portfolio’s investment exposures exceed its net asset value), which may amplify the Portfolio’s gains and losses and cause the Portfolio to be more volatile and riskier than if it had not been leveraged.
PSF PGIM High Yield Bond Portfolio | Liquidity And Valuation Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Liquidity and Valuation Risk. The Portfolio may hold one or more securities for which there are no or few buyers and sellers or the securities are subject to limitations on transfer. The Portfolio may be unable to sell those portfolio holdings at the desired time or price, and may have difficulty determining the value of such securities for the purpose of determining the Portfolio’s net asset value. In such cases, investments owned by the Portfolio may be valued at fair value pursuant to policies and procedures adopted and implemented by the Manager. No assurance can be given that the fair value prices accurately reflect the value of the security. The Portfolio is subject to a liquidity risk management program, which limits the ability of the Portfolio to invest in illiquid investments.
PSF PGIM High Yield Bond Portfolio | Loan Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Loan Risk. A Portfolio's ability to receive payments of principal and interest and other amounts in connection with loans (whether through participations, assignments or otherwise) will depend primarily on the financial condition of the borrower. The failure by the Portfolio to receive scheduled interest or principal payments on a loan because of a default, bankruptcy or any other reason would adversely affect the income of the Portfolio and would likely reduce the value of its assets. Even with loans secured by collateral, there is the risk that the value of the collateral may decline, may be insufficient to meet the obligations of the borrower, or be difficult to liquidate. In the event of a default, the Portfolio may have difficulty collecting on any collateral and would not have the ability to collect on any collateral for an uncollateralized loan. Further, the Portfolio's access to collateral, if any, may be limited by bankruptcy laws. Loans that are secured and senior to other debtholders of a borrower tend to have more favorable loss recovery rates as compared to more junior types of below investment grade debt obligations, and junior loans can involve a higher degree of risk than more senior loans. In addition, loan participations generally are subject to restrictions on transfer, and only limited opportunities may exist to sell loan participations in secondary markets. As a result, it may be difficult for the Portfolio to value loans or sell loans at an acceptable price when it wants to sell them. Loans trade in an over-the-counter market, and confirmation and settlement, which are effected through standardized procedures and documentation, may have an impact on the length and timing of completing trades. To the extent the Portfolio invests in loans of non-US issuers, the risks of investing in non-US issuers are applicable. Loans may not be considered to be “securities” and as a result may not benefit from the protections of the federal securities laws, including anti-fraud protections and those with respect to the use of material non-public information, so that purchasers, such as the Portfolio, may not have the benefit of these protections.
PSF PGIM High Yield Bond Portfolio | Market And Management Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market and Management Risk. Markets in which the Portfolio invests may experience volatility and go down in value, and possibly sharply and unpredictably in short periods of time. Investment techniques, risk analyses, and investment strategies, which may include quantitative models or methods, used by a subadviser in making investment decisions for the Portfolio are subject to human error and may not produce the intended or desired results. While a Portfolio Manager or Subadviser(s) may make efforts to control the risks associated with market changes, and may attempt to identify changes as they occur, market environment changes can be sudden and extreme. The value of the Portfolio’s investments may be negatively affected by the occurrence of domestic or global events, including war, terrorism, significant or unexpected failures, near-failures or credit downgrades of key institutions, unexpected changes in the prices of key commodities, government actions, environmental disasters, natural disasters, sanctions, cybersecurity events, supply chain disruptions, political or civil instability, and public health emergencies, among others. Such events may reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, and significantly adversely impact the economy. These events can adversely affect the liquidity and volatility of investments held by the Portfolio, and there is no guarantee that the investment objective of the Portfolio will be achieved. In periods of market volatility and/or declines, the Portfolio may experience high levels of shareholder redemptions, and may have to sell securities at times when it would otherwise not do so, and at unfavorable prices.
PSF PGIM High Yield Bond Portfolio | Prepayment Or Call Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Prepayment or Call Risk. Prepayment or call risk is the risk that issuers will prepay fixed-rate obligations held by the Portfolio when interest rates fall, forcing a Portfolio to reinvest in obligations with lower interest rates than the original obligations. Mortgage-related securities and asset-backed securities are particularly subject to prepayment risk.
PSF PGIM High Yield Bond Portfolio | Regulatory Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Regulatory Risk. The Portfolio is subject to a variety of laws and regulations which govern its operations. The Portfolio is subject to regulation by the Securities and Exchange Commission (the SEC), and depending on the Portfolio, the Commodity Futures Trading Commission (the CFTC). Similarly, the businesses and other issuers of the securities and other instruments in which the Portfolio invests are also subject to considerable regulation. Changes in laws and regulations may materially impact the Portfolio, a security, business, sector, or market.
PSF PGIM High Yield Bond Portfolio | Reverse Repurchase Agreement Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Reverse Repurchase Agreement Risk: Reverse repurchase agreements involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. The use of reverse repurchase agreements may exaggerate any increase or decrease in the value of a Portfolio’s assets. The use of reverse repurchase agreements is a form of leverage because the proceeds derived from reverse repurchase agreements may be invested in additional securities.
PSF PGIM High Yield Bond Portfolio | Short Sale Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Short Sale Risk. A short sale involves the risk that the price of a borrowed security will increase during the time the Portfolio has borrowed the security and the Portfolio will incur a loss equal to the increase in price from the time that the short sale was entered into plus any premiums and interest paid to the third party. Short sales may result in losses that are greater than the cost of the investment. In addition, the third party to the short sale may fail to honor its contract terms, causing a loss to the Portfolio.

[1] The Manager has contractually agreed to waive a portion of its management fee and/or reimburse certain expenses of the Portfolio so that the Portfolio’s management fee plus other expenses (exclusive of certain expenses as described more fully in the Trust’s Statement of Additional Information) do not exceed 0.57% of the Portfolio's average daily net assets through June 30, 2026. Where applicable, the Manager agrees to waive management fees or shared operating expenses on any share class to the same extent that it waives such expenses on any other share class. Expenses waived/reimbursed by the Manager for the purpose of preventing the expenses from exceeding a certain expense ratio limit may be recouped by the Manager within the same fiscal year during which such waiver/reimbursement is made if such recoupment can be realized without exceeding the expense limit in effect at the time of the waiver/reimbursement and/or recoupment for that fiscal year, as applicable. These arrangements may not be terminated or modified without the prior approval of the Trust's Board.
