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.

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	The Portfolio invests at least 99.5% of its total assets in cash, government securities, and/or repurchase agreements that are fully collateralized with cash or government securities. Government securities include US Treasury bills, notes, and other obligations issued or guaranteed as to principal and interest by the US Government or its agencies or instrumentalities. The Portfolio has a policy that requires it to invest under normal conditions, at least 80% of its net assets in government securities and/or repurchase agreements that are collateralized by government securities.In managing the Portfolio’s assets, the subadviser 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 is 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.The Portfolio invests only in securities that have remaining maturities of 397 days or less, or securities otherwise permitted to be purchased because of maturity shortening provisions under applicable regulations. The Portfolio seeks to invest in securities that present minimal credit risk. The Portfolio may invest significantly in securities with floating or variable rates of interest.The Portfolio seeks to maintain a stable net asset value of $10.00 per share. In other words, the Portfolio attempts to operate so that shareholders do not lose any of the principal amount they invest in the Portfolio. Of course, there can be no assurance that the Portfolio will achieve its goal of a stable net asset value, and shares of the Portfolio are neither insured nor guaranteed by the US government or any other entity. For instance, the issuer or guarantor of a portfolio security or the other party to a contract could default on its obligation, and this could cause the Portfolio's net asset value per share to fall below $10.00. In addition, the income earned by the Portfolio will fluctuate based on market conditions, interest rates and other factors.In a low interest rate environment, the yield of the Portfolio, after the deduction of operating expenses, may be negative even though the yield before deducting such expenses is positive. A negative yield may also cause the Portfolio's net asset value per share to fall below $10.00. PGIM Investments LLC may decide to reimburse certain of these expenses to the Portfolio in order to maintain a positive yield, however it is under no obligation to do so and may cease doing so at any time without prior notice.The Trust’s Board of Trustees (the Board) has determined that the Portfolio, as a “government money market fund”, is not subject to liquidity fees and/or redemption gates on redemptions. The Board has reserved the power to change this determination with respect to liquidity fees and/or redemption gates, but such change would become effective only after providing appropriate prior notice to shareholders.
Risk [Heading]	rr_RiskHeading	<span style="font-family:Arial;font-size:10pt;font-weight:bold;margin-left:0%;">Principal Risks of Investing in the Portfolio.</span>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The risks summarized below are the principal risks of investing in the Portfolio. You could lose money by investing in the Portfolio.Although the Portfolio seeks to preserve the value of your investment at $10.00 per share, it cannot guarantee it will do so.An investment in the Portfolio is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.The Portfolio’s sponsor has no legal obligation to provide financial support to the Portfolio, and you should not expect that the sponsor will provide financial support to the Portfolio at any time. The order of the below risk factors does not indicate the significance of any particular risk factor.Adjustable and Floating-Rate Securities Risk. The value of adjustable and floating-rate securities may lag behind the value of fixed-rate securities when interest rates change. Variable and floating-rate bonds are subject to credit risk, market risk and interest rate risk. In addition, the absence of an active market for these securities could make it difficult for the Portfolio to dispose of them if the issuer defaults.Credit Risk. This is the risk that the issuer, the guarantor or the insurer of a fixed income security, or the counterparty to a contract, may be unable or unwilling to make timely principal and interest payments, or to otherwise honor its obligations. Additionally, fixed income securities could lose value due to a loss of confidence in the ability of the issuer, guarantor, insurer or counterparty to pay back debt. The longer the maturity and the lower the credit quality of a bond, the more sensitive it is to credit risk.Economic and Market Events Risk. Events in the US and global financial markets, including actions taken by the US Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in periods of unusually high volatility in a market or a segment of a market, which could negatively impact performance. Reduced liquidity in credit and fixed income markets could adversely affect issuers worldwide.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.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. Risks associated with changing interest rates are currently heightened because any increase or decrease may be sudden and significant, with unpredictable effects on the markets and the Portfolio’s investments. Changes in interest rates may also affect the liquidity of the Portfolio’s investments in fixed income securities.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.” The Portfolio currently faces a heightened level of interest rate risk because interest rates in the US are at or near historic lows. Interest rates may begin to increase in the future, possibly suddenly and significantly, with unpredictable effects on the markets and the Portfolio’s investments. The Portfolio may lose money if short-term or long-term interest rates rise sharply or in a manner not anticipated by the subadviser.Market and Management Risk. Markets in which the Portfolio invests may experience volatility and go down in value, and possibly sharply and unpredictably. 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. The value of the Portfolio’s investments may be negatively affected by the occurrence of domestic or global events,including war, terrorism, environmental disasters, natural disasters or events, political or civil instability, and public health emergencies (such as the spread of infectious diseases, pandemics, or epidemics), 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. There is no guarantee that the investment objective of the Portfolio will be achieved.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.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 SEC, and depending on the Portfolio, 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.US Government Securities Risk. US Government securities may be adversely affected by changes in interest rates, a default by, or decline in the credit quality of, the US Government, and may not be backed by the full faith and credit of the US Government.Yield Risk. The amount of income received by a Portfolio will go up or down depending on day-to-day variations in short-term interest rates, and when interest rates are very low, the Portfolio’s expenses could absorb all or a significant portion of the Portfolio’s income. If interest rates increase, the Portfolio’s yield may not increase proportionately. For example, the Portfolio’s investment manager may discontinue any temporary voluntary fee limitation.

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 measure of market performance.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 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.Note: Prior to September 12, 2016, the Portfolio operated under the name “Money Market Portfolio” as a prime money market fund and invested in certain types of securities that, as a government money market fund, the Portfolio is no longer permitted to hold. Consequently, the performance information below may have been different if the current investment limitations had been in effect during the period prior to the Portfolio’s conversion to a government money market fund.
