Product details
Overview
IRFR9020TRL from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in DPAK (TO-252) surface-mount package, rated for -50 V VDS, 0.28 Ω RDS(on) at VGS = -10 V, and -9.9 A continuous drain current at TC = 25 °C. It delivers robust avalanche capability (EAS = 250 mJ), fast switching (tr = 57–66 ns), and low gate charge (Qg = 14 nC max), making it suitable for DC/DC converter high-side switches and synchronous rectification in telecom power supplies.
For engineers reviewing the IRFR9020TRL datasheet, IRFR9020TRL pinout, IRFR9020TRL application, or IRFR9020TRL equivalent, key selection considerations include its -50 V blocking rating, DPAK thermal performance (RthJC = 3.0 °C/W), body diode recovery time (trr = 56–280 ns), and Pb-free/halogen-free compliance per JEDEC TO-252AA standards.
Technical Context
This device uses planar V-groove trench-enhanced P-channel MOSFET technology optimized for low RDS(on) and high transconductance (gfs = 3.5 S typ). Its gate threshold voltage (VGS(th) = -2.0 to -4.0 V) ensures reliable turn-on with standard -10 V logic-level drive while maintaining noise immunity.
The integrated body diode supports unidirectional freewheeling in buck converters and reverse-polarity protection circuits. Its dV/dt rating (5.8 V/ns) and repetitive avalanche capability (IAR = -9.9 A) enable operation in inductive switching environments without external snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -50 V - Maximum drain-source blocking voltage for high-side switch placement in ≤48 V systems |
| RDS(on) @ VGS = -10 V | 0.28 Ω max - Enables ≤2.8 W conduction loss at -9.9 A, critical for thermally constrained PCBs |
| Qg | 14 nC max - Reduces gate driver power demand and enables <12 ns turn-on delay with 18 Ω Rg |
| tr / tf | 57–66 ns / 25–38 ns - Supports >500 kHz switching in isolated DC/DC topologies with minimal overlap loss |
| EAS | 250 mJ - Withstands single-pulse inductive energy without failure in unclamped inductive load tests |
| RthJC | 3.0 °C/W max - Allows 42 W power dissipation with ≤126 °C junction rise above 25 °C case temperature |
| trr | 56–280 ns - Limits reverse recovery charge (Qrr = 0.17–0.85 nC) to reduce EMI and cross-conduction risk |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRFR9024TRPbF | VDS = -60 V, RDS(on) = 0.33 Ω @ -10 V, Qg = 16 nC - higher voltage rating but 18% higher on-resistance | Better suited for 60 V industrial buses; less efficient in 48 V telecom rails due to higher conduction loss | Select IRFR9024TRPbF only when system requires >50 V blocking margin; IRFR9020TRL offers superior thermal performance at 48 V. |
| SiHFR9020-GE3 | Identical electrical specs and DPAK package; differs only in Vishay's internal process flow and traceability coding | No functional or layout impact; fully interchangeable in production with same thermal and switching behavior | SiHFR9020-GE3 is a second-source option with identical performance; choose based on supply chain availability, not design trade-offs. |
Compared with IRFR9024TRPbF, IRFR9020TRL delivers lower conduction loss in 48 V systems and faster switching due to reduced Qg; versus SiHFR9020-GE3, it shares identical die and package but differs in manufacturing lot traceability and Pb-free marking convention.

FAQ
What is the maximum continuous drain current for IRFR9020TRL at 100 °C case temperature?
The IRFR9020TRL supports -6.3 A continuous drain current at TC = 100 °C, derived from its 42 W maximum power dissipation and 0.33 W/°C linear derating factor. This value reflects real-world thermal limits when mounted on FR-4 PCBs with 1"² copper area, ensuring safe operation in enclosed telecom enclosures without forced air cooling. The IRFR9020TRL datasheet specifies this rating in Absolute Maximum Ratings Table, footnote "TC = 100 °C".
Does IRFR9020TRL have a built-in body diode, and what are its key parameters?
Yes, the IRFR9020TRL integrates a monolithic p-n junction body diode with -9.9 A continuous forward current rating, -6.3 V forward voltage at -9.9 A and 25 °C, and reverse recovery time of 56–280 ns. Its Qrr is 0.17–0.85 nC, enabling use in synchronous rectification without external diodes. These values are measured per the test conditions in the "Drain-source body diode characteristics" section of the IRFR9020TRL datasheet.
Can IRFR9020TRL be used in avalanche mode, and what are its repetitive avalanche ratings?
Yes, the IRFR9020TRL is rated for repetitive avalanche operation with IAR = -9.9 A and EAR = 4.2 mJ per pulse, limited by junction temperature. Its single-pulse avalanche energy is 250 mJ. These ratings assume pulse width constraints defined in Figure 16 and are validated per the unclamped inductive test circuit in Figure 14. The IRFR9020TRL's avalanche capability is explicitly documented in the Absolute Maximum Ratings table and confirmed in the "Repetitive avalanche current" footnote "a".
What is the gate threshold voltage range for IRFR9020TRL, and how does it affect drive requirements?
The IRFR9020TRL has a gate-source threshold voltage (VGS(th)) range of -2.0 V to -4.0 V at ID = -50 μA, ensuring reliable turn-on with standard -10 V logic-level gate drivers while rejecting noise below -2 V. This range allows compatibility with both dedicated MOSFET drivers and microcontroller GPIOs with sufficient sink capability. The IRFR9020TRL's VGS(th) is specified in the "Static" section of the Electrical Characteristics table.
Is IRFR9020TRL compatible with lead-free reflow soldering processes?
Yes, the IRFR9020TRL is Pb-free and halogen-free, qualified for JEDEC J-STD-020D reflow profiles with peak temperatures up to 260 °C for 10 seconds. Its DPAK (TO-252AA) package meets IPC-7095 guidelines for surface-mount thermal management, and the device is marked "TRLPbF" to indicate lead-free compliance. This information is confirmed in the Ordering Information table and Package Information document 71197.
