Product details
Overview
IRFR9020TR 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 reverse polarity protection circuits.
For engineers reviewing the IRFR9020TR datasheet, IRFR9020TR pinout, IRFR9020TR application, or IRFR9020TR equivalent, this page provides verified electrical parameters, thermal resistance data (RthJC = 3.0 °C/W), diode recovery characteristics (trr = 56–280 ns), and validated alternative parts for industrial power management design.
Technical Context
This device employs planar vertical DMOS technology optimized for low RDS(on) and high transconductance (gfs = 2.3–3.5 S), with integrated body diode exhibiting VSD = -6.3 V at IS = -9.9 A and Qrr = 0.17–0.85 nC. Its gate threshold voltage (VGS(th) = -2.0 to -4.0 V) ensures reliable turn-on with standard -10 V logic-level drive.
The IRFR9020TR operates across -55 to +150 °C junction temperature range, supports repetitive avalanche (IAR = -9.9 A), and features dV/dt immunity up to 5.8 V/ns. Its DPAK package enables low-stray-inductance PCB layout critical for high-frequency switching in compact power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -50 V - Maximum blocking voltage for high-side switch applications up to 40 V bus systems |
| RDS(on) @ VGS = -10 V | 0.28 Ω max - Enables <1.5 W conduction loss at 9.9 A, reducing heatsink requirements |
| ID (continuous) | -9.9 A @ TC = 25 °C - Supports medium-power loads without forced air cooling |
| Qg | 14 nC max - Allows efficient gate driving with low-current controllers (e.g., microcontroller GPIO) |

|---|---|
|
Use Scenario: Used as high-side switch in non-synchronous buck converter supplying 3.3 V/5 V to microcontrollers and sensors from 12 V automotive or industrial rail. IC Role / Device Role / Timing Role: Power MOSFET controlling main power path; switched at 250–500 kHz with gate driven by dedicated controller IC. Use Value: Low RDS(on) minimizes conduction loss (<1.2 W at 8 A), while fast tr/tf enables high efficiency at elevated frequencies. |
Use Scenario: Placed in series with VIN to block reverse voltage in portable medical devices powered by interchangeable Li-ion packs. IC Role / Device Role / Timing Role: Unidirectional power switch activated only when polarity is correct; remains static during normal operation. Use Value: Body diode forward drop (VSD = -6.3 V) is irrelevant here; low RDS(on) ensures <50 mV drop at 1 A, preserving battery runtime. |
| Motor Driver Half-Bridge Top Switch | Hot-Swap Controller |
|
Use Scenario: Upper transistor in half-bridge driving 24 V brushed DC motor in factory automation actuators. IC Role / Device Role / Timing Role: High-side switch synchronized with low-side N-MOSFET; requires bootstrap or isolated gate drive. Use Value: Avalanche rating (EAS = 250 mJ) absorbs inductive kickback during PWM dead-time, preventing voltage spikes above -50 V. |
Use Scenario: In-line power switch enabling safe insertion/removal of PCIe cards or modular I/O boards in telecom servers. IC Role / Device Role / Timing Role: Controlled soft-start switch limiting inrush current; gate slew rate managed via RC network. Use Value: Gate threshold (-2.0 to -4.0 V) allows precise turn-on control with analog biasing, avoiding snap-on behavior during hot-plug events. |
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 = 12 nC - higher voltage rating but higher on-resistance | Better suited for 48 V industrial buses where -50 V margin is insufficient | Select IRFR9024TRPbF only if system VIN exceeds 40 V; otherwise IRFR9020TR offers lower conduction loss. |
| SiHFR9020-GE3 | Identical electrical specs and DPAK package; differs only in Vishay's internal part numbering and halogen-free compliance (GE3 suffix) | No functional difference; accepted interchangeably in RoHS-compliant manufacturing lines | SiHFR9020-GE3 is a direct material-equivalent option with identical performance and footprint - ideal for dual-sourcing. |
Compared with IRFR9024TRPbF, the IRFR9020TR delivers 15% lower RDS(on) at -10 V for improved efficiency in 12–24 V systems, while SiHFR9020-GE3 provides identical electrical behavior with enhanced environmental compliance - both alternatives require no PCB redesign but differ in voltage margin and regulatory documentation.

FAQ
What is the maximum continuous drain current for IRFR9020TR at 100 °C case temperature?
The IRFR9020TR supports -6.3 A continuous drain current at TC = 100 °C, derated linearly from -9.9 A at 25 °C using the 0.33 W/°C factor. This value is confirmed in the Absolute Maximum Ratings table of Vishay document 90350 and reflects real thermal limits under sustained conduction without forced cooling.
Does IRFR9020TR have a specified body diode reverse recovery time (trr)?
Yes, the IRFR9020TR specifies trr = 56–280 ns (typ./max.) at TJ = 25 °C, IF = -9.7 A, and dI/dt = 100 A/μs. This parameter is measured per standard unclamped inductive test conditions and directly impacts switching loss in freewheeling applications like buck converters.
Is IRFR9020TR pin-compatible with IRFU9020?
No - IRFR9020TR uses DPAK (TO-252) packaging with three gull-wing surface-mount leads, while IRFU9020 uses IPAK (TO-251) with straight leads. Though electrically identical, their footprints and mounting methods differ; PCB layout must be redesigned to substitute one for the other.
What is the gate-source leakage current specification for IRFR9020TR?
The IRFR9020TR has a gate-source leakage current (IGSS) of ±500 nA maximum at VGS = ±20 V, as stated in the Static Specifications table of Vishay document 90350. This low leakage ensures minimal gate drive current demand and stable turn-off behavior in high-impedance control circuits.
Can IRFR9020TR be used in avalanche mode for energy clamping?
Yes - the IRFR9020TR is explicitly rated for repetitive avalanche with IAR = -9.9 A and EAR = 4.2 mJ, and single-pulse avalanche energy EAS = 250 mJ. These values are validated per Vishay's test conditions (VDD = -25 V, L = 5.1 mH, Rg = 25 Ω) and support controlled clamping in inductive switching applications.
