| Factors Affecting Performance [Text Block] | WHAT AFFECTED THE FUND’S PERFORMANCE DURING THE REPORTING PERIOD? ■ Capital asset prices increased over the reporting period as investors reacted positively to the slowing pace of inflation and sustained economic growth. The US Federal Reserve moved to lower the federal funds rate by 50 basis points at its September meeting and by another 25 basis points at its November meeting. (One basis point equals 0.01%.) Equities responded favorably to the moves, especially interest-rate-sensitive sectors of the market. Financial stocks (as represented by the S&P Composite 1500 Financials Index) generally outperformed the overall equity market (as represented by the S&P 500 Index). ■ The Fund’s security selection within capital markets (led by KKR & Co. Inc. and The Goldman Sachs Group Inc.), financial services (especially Apollo Global Management Inc.), and insurance (driven by Ryan Specialty Holdings Inc. and The Progressive Corp.) were the largest contributors to the Fund’s solid performance and its significant outperformance relative to the Index. An underweight in financial services and an overweight in banks also bolstered relative results. ■ On the negative side, stock selection in the banking industry, along with overweights in insurance and mortgage REITs, and non-Index positions in consumer discretionary, detracted the most. |

| Factors Affecting Performance [Text Block] | WHAT AFFECTED THE FUND’S PERFORMANCE DURING THE REPORTING PERIOD? ■ Capital asset prices increased over the reporting period as investors reacted positively to the slowing pace of inflation and sustained economic growth. The US Federal Reserve moved to lower the federal funds rate by 50 basis points at its September meeting and by another 25 basis points at its November meeting. (One basis point equals 0.01%.) Equities responded favorably to the moves, especially interest-rate-sensitive areas of the market. Health care stocks (as represented by the S&P Composite 1500 Health Care Index (Index)) generally underperformed the overall equity market (as represented by the S&P 500 Index). ■ The Fund’s holdings within pharmaceuticals (especially Bristol-Myers Squibb Co. and Verona Pharma plc), biotechnology (led by Arcutis Biotherapeutics Inc. and Crinetics Pharmaceuticals Inc.), and medtech (driven by DexCom Inc. and Boston Scientific Corp.) were the largest contributors to the Fund’s solid performance and its significant outperformance relative to the Index. ■ On the negative side, stock selection in health care providers & services (especially Humana Inc. and UnitedHealth Group Inc.), along with an underweight in medtech relative to the Index, detracted the most. |

| Expenses [Text Block] | WHAT WERE THE FUND COSTS FOR THE LAST YEAR? (Based on a hypothetical $10,000 investment) Costs of a $10,000 investment Costs paid as a percentage of a $10,000 investment PGIM Jennison Utility Fund—Class R $133 1.11% |
| Expenses Paid, Amount | $ 133 |
| Expense Ratio, Percent | 1.11% |
| Factors Affecting Performance [Text Block] | WHAT AFFECTED THE FUND’S PERFORMANCE DURING THE REPORTING PERIOD? ■ Capital asset prices increased over the reporting period as investors reacted positively to the slowing pace of inflation and sustained economic growth. The US Federal Reserve moved to lower the federal funds rate by 50 basis points at its September meeting and by another 25 basis points at its November meeting. (One basis point equals 0.01%.) Equities responded favorably to the moves, particularly interest-rate-sensitive sectors of the market. Utility stocks (as represented by the S&P 500 Utilities Index (Index)) outperformed the overall equity market (as represented by the S&P 500 Index). ■ Within utilities, positions in independent power producers and renewables (led by Vistra Corp. and Talen Energy Corp.) and out-of-Index exposure to water utilities contributed positively to the Fund’s performance relative to the Index. Energy sector names (primarily Targa Resources Corp.) further bolstered relative results. ■ On the negative side, security selection in electric utilities and multi-utilities, along with exposure to out-of-Index names in communications, detracted the most. |
