Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	The table below shows the fees and expenses that you may pay if you invest in shares of the Portfolio. 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 table. See your Contract prospectus for more information about Contract charges.

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 102% 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 common stock. The Portfolio primarily invests in the stock of companies with market capitalizations within the market capitalization range of the Russell 1000® Index (measured at the time of purchase). The market capitalization within the range will vary, but as of January 27, 2025, the weighted average market capitalization of companies included in the Russell 1000® Index was approximately $967 billion, and the market capitalization of the largest company included in the Russell 1000® Index was approximately $3.4 trillion. In addition, the Portfolio may invest in mid- and small-capitalization companies. The Portfolio’s subadviser, Jennison Associates LLC, employs a bottom-up fundamental stock research process which sources the investment universe from Jennison’s growth, value, and small/mid cap investment teams. The growth research team seeks companies with unique business models with sustained competitive advantages; catalysts that drive growth rates well above that of the market; superior financial characteristics; and attractive long-term valuations. The value research team seeks companies the team believes are being valued at a discount to their intrinsic value, seeking companies with attractive valuation metrics that are unique to that business, high levels of durability and viability of the business and good business models that are being mispriced. The small/mid cap research process is designed to capitalize on inefficiencies in small-cap asset classes, seeking companies with attractive valuations, strong competitive positions, quality management teams, demonstrated growth in sales and earnings, balance sheet flexibility and strength, and strong earnings growth prospects. The Portfolio may invest up to 30% of its total assets in foreign securities (not including American Depositary Receipts and similar instruments). Up to 20% of the Portfolio’s investable assets may be invested in short-, intermediate- or long-term debt obligations, convertible and nonconvertible preferred stock and other equity-related securities. Up to 5% of these investable assets may be rated below investment grade. These securities are considered speculative and are sometimes referred to as “junk bonds.” The subadviser employs a systematic portfolio construction process to incorporate its fundamental analysis with a systematic analysis of factors, such as stock price momentum and stock valuation. Incorporating information from both the subadviser’s fundamental and systematic analyses, the subadviser constructs a diversified portfolio with sector and risk factor exposures managed relative to the Russell 1000® Index, using a technique known generally as portfolio optimization.

Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and table provide some indication of the risks of investing in the Portfolio by showing changes in the Portfolio's performance from year to year and by showing how the Portfolio's average annual returns for 1, 5, and 10 years compare with those of a broad-based securities market index that reflects the performance of the overall market applicable to the Portfolio and an additional index that represents the market sectors in which the Portfolio primarily invests.Past performance does not mean that the Portfolio will achieve similar results in the future.The annual returns and average annual returns shown in the chart and table are after deduction of expenses and do not include Contract charges. 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 II and Class III shares would be lower because Class II and Class III shares do not have the same expenses as Class I shares. Note: The PSF PGIM Jennison Blend Portfolio changed certain investment strategies, effective December 11, 2023. The performance figures prior to December 11, 2023 for the Portfolio reflect the Portfolio's former investment operations, policies, and strategies prior to this date. Such performance is not representative of the Portfolio’s current investment operations, policies, and strategies that took effect as of this date, and the Portfolio's performance after this date could be materially different.

PSF PGIM Jennison Blend 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 Jennison Blend 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 Jennison Blend Portfolio | Equity Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Equity Securities Risk. The value of a particular stock or equity-related security held by the Portfolio could fluctuate, perhaps greatly, in response to a number of factors, such as changes in the issuer’s financial condition or the value of the equity markets or a sector of those markets. 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 Jennison Blend Portfolio | Blend Style Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Blend Style Risk. A Portfolio's blend investment style may subject the Portfolio to risks of both value and growth investing. The portion of the Portfolio's portfolio that makes investments pursuant to a growth strategy may be subject to above-average market price fluctuations as a result of seeking high-quality stocks with good future growth prospects. The portion of the Portfolio's portfolio that makes investments pursuant to a value strategy may be subject to the risk that the market may not recognize a security's intrinsic value for long periods of time or that a stock judged to be undervalued may actually be appropriately priced. Issuers of value stocks may have experienced adverse business developments or may be subject to special risks that have caused the stock to be out of favor. If the Portfolio's assessment of market conditions or a company’s value is inaccurate, the Portfolio could suffer losses or produce poor performance relative to other funds. Historically, growth stocks have performed best during later stages of economic expansion and value stocks have performed best during periods of economic recovery. Therefore, both styles may over time go in and out of favor depending on market conditions. At times when a style is out of favor, that portion of the portfolio may lag the other portion of the portfolio, which may cause the Portfolio to underperform the market in general, its benchmark, and other mutual funds.
PSF PGIM Jennison Blend 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 Jennison Blend 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 Jennison Blend 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 Jennison Blend 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 Jennison Blend 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 Jennison Blend 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 Jennison Blend Portfolio | Large Company Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Large Company Risk. Large-capitalization stocks as a group could fall out of favor with the market, causing the Portfolio to underperform investments that focus on small- or medium-capitalization stocks. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies. Investments in securities of certain issuers with the largest market capitalizations can result in greater investment exposure to a limited number of issuers and sectors, primarily the technology sector, which can result in greater losses in the event of a market downturn or deteriorating fundamentals in those issuers or sectors.
PSF PGIM Jennison Blend 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 Jennison Blend Portfolio | Mid Sized Company Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Mid-Sized Company Risk. The shares of mid-sized companies tend to trade less frequently than those of larger, more established companies, which can have an adverse effect on the pricing and volatility of these securities and on the Portfolio’s ability to sell the securities.
PSF PGIM Jennison Blend Portfolio | Small Sized Company Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Small Sized Company Risk. Securities of small sized companies tend to be less liquid than those of larger, more established companies, which can have an adverse effect on the price of these securities and on the Portfolio’s ability to sell these securities. The market price of such investments also may rise more in response to buying demand and fall more in response to selling pressure and be more volatile than investments in larger companies. Investing in issuers within the same market capitalization category carries the risk that the category may be out of favor due to current market conditions or investor sentiment.
PSF PGIM Jennison Blend 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 Jennison Blend 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.

[1] Any differences in total annual portfolio operating expenses shown in the table above and the expense ratio (after waivers and/or reimbursements) in the Portfolio’s Financial Highlights are attributable to changes in management fees, fee waivers and/or expense limitations occurring after the end of the most recent fiscal year. Total Annual Portfolio Operating Expenses (both before and after fee waivers and/or expense reimbursements) have been restated to reflect current expenses and fee waivers/reimbursements.
