Product details

Overview

IRFR9220TR from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in DPAK (TO-252) surface-mount package, rated for -200 V drain-source voltage, 1.5 Ω R_DS(on) at V_GS = -10 V, and -3.6 A continuous drain current at T_C = 25 °C. It delivers fast switching with 20 nC total gate charge and supports repetitive avalanche operation up to 4.2 mJ, making it suitable for high-voltage DC-DC converters and industrial motor control.

For engineers reviewing the IRFR9220TR datasheet, IRFR9220TR pinout, IRFR9220TR application, or IRFR9220TR equivalent, this page provides verified technical context, validated pin configuration, real-world use cases in high-side switching and polarity-reversal circuits, and confirmed alternative parts with documented functional and packaging differences.

Technical Context

This device uses Vishay's third-generation Power MOSFET technology to achieve low on-resistance while maintaining ruggedness against unclamped inductive switching. Its P-channel architecture enables high-side switch configurations without level-shifting circuitry, and its -200 V V_DS rating supports operation in 100–150 V bus systems with margin.

The IRFR9220TR features dynamic dV/dt immunity (-5.0 V/ns), integrated body diode with 150–300 ns reverse recovery time, and thermal resistance of 3.0 °C/W junction-to-case - enabling stable operation under pulsed loads when mounted on heatsinked PCBs or metal-core substrates.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-200 V - supports 150 V nominal bus applications with 33 % voltage margin for transients
R_DS(on)	1.5 Ω @ V_GS = -10 V - limits conduction loss to ≤ 19.4 W at -3.6 A, enabling compact thermal design
Q_g	20 nC - determines gate drive power requirement; compatible with standard logic-level drivers
I_D (cont.)	-3.6 A @ T_C = 25 °C - defines maximum steady-state current in heatsinked DPAK mounting
E_AS	310 mJ - enables robust handling of unclamped inductive energy in relay/snubberless designs
R_thJC	3.0 °C/W - allows direct thermal path to heatsink via exposed drain pad, critical for >1 W dissipation
V_GS(th)	-2.0 to -4.0 V - ensures reliable turn-on with -5 V or -10 V gate drive, avoiding partial enhancement

Pinout & Package

DPAK (TO-252) package with exposed drain pad on bottom side for thermal conduction; three terminals: Gate (G), Drain (D), Source (S); standardized footprint per JEDEC MO-236AB.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate	Controls channel conduction; requires -10 V for full enhancement; input capacitance C_iss = 340 pF affects switching speed
D	Drain	High-voltage terminal connected to exposed copper pad; serves as primary thermal path to PCB heatsink
S	Source	Reference node for gate drive; body diode anode; tied to system ground or positive rail in high-side topology

Key Features

Feature	Design Value
Repetitive avalanche rated	Withstands 4.2 mJ repeated avalanche events without degradation - eliminates need for external snubbers in inductive load switching
Dynamic dV/dt immunity	-5.0 V/ns - prevents false turn-on during high dv/dt transients in motor drive or SMPS output stages
Surface-mount DPAK	TO-252 outline with thermal pad - enables automated assembly and 2.5 W PCB-mount power dissipation per Vishay spec
Fast switching	Turn-off delay 7.3 ns + fall time 19 ns - reduces switching losses in 100–500 kHz DC-DC topologies
P-channel configuration	Enables high-side switch without bootstrap or isolated gate drive - simplifies layout in battery polarity protection and OR-ing circuits

FAQ

What is the maximum continuous drain current for IRFR9220TR at 100 °C case temperature?

The IRFR9220TR supports -2.3 A continuous drain current at T_C = 100 °C, per its Absolute Maximum Ratings table. This derating reflects thermal limitations of the DPAK package; designers must ensure adequate heatsinking or PCB copper area to maintain case temperature below this threshold during sustained operation. The linear derating factor is 0.33 W/°C above 25 °C ambient.

Does IRFR9220TR have a specified avalanche energy rating?

Yes, the IRFR9220TR is repetitively avalanche rated with E_AR = 4.2 mJ and single-pulse E_AS = 310 mJ. These values are measured under defined test conditions (V_DD = -50 V, L = 35 mH, R_g = 25 Ω, I_AS = -3.6 A) and confirm its ability to absorb inductive energy without failure - a key differentiator for relay driving and motor control.

What is the gate-source threshold voltage range for IRFR9220TR?

The IRFR9220TR has a gate-source threshold voltage V_GS(th) ranging from -2.0 V to -4.0 V at T_J = 25 °C, with ID = -250 μA. This ensures reliable turn-on with standard -5 V or -10 V gate drive while preventing accidental conduction near 0 V. The negative polarity confirms its P-channel nature and distinguishes it from N-channel alternatives.

Can IRFR9220TR be used in through-hole applications?

No, the IRFR9220TR is specifically a surface-mount DPAK (TO-252) variant. Through-hole equivalents include IRFU9220 (IPAK/TO-251) and SiHFU9220 - both share identical electrical specs but differ in package and mounting method. Substituting IRFR9220TR into a through-hole footprint will result in mechanical incompatibility and solder joint failure.

What is the thermal resistance from junction to case for IRFR9220TR?

The IRFR9220TR has a maximum junction-to-case (drain) thermal resistance R_thJC of 3.0 °C/W. This value applies to heat flow from the silicon die to the exposed drain pad, and is critical for calculating junction temperature when the device is mounted on a heatsink or thermally enhanced PCB. It assumes proper soldering of the drain pad per Vishay's recommended land pattern.
