Product details
Overview
IRFR9220 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 RDS(on) at VGS = -10 V, and -3.6 A continuous drain current at TC = 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 motor control circuits.
For engineers reviewing the IRFR9220 datasheet, IRFR9220 pinout, IRFR9220 application, or IRFR9220 equivalent, key selection criteria include its -200 V blocking capability, low gate charge for efficient PWM drive, thermal performance on PCB mount (RthJA = 50 °C/W), and body diode recovery characteristics (trr = 150–300 ns).
Technical Context
This device uses Vishay's third-generation Power MOSFET technology optimized for ruggedness and low conduction loss. Its P-channel architecture enables high-side switching without level-shifting circuitry, and its dynamic dV/dt rating (-5.0 V/ns) ensures reliable operation under fast transient conditions.
The IRFR9220 integrates a robust intrinsic body diode with -6.3 V forward voltage at -3.6 A and 2.0 μC reverse recovery charge. Its SOA curve supports unclamped inductive switching up to 310 mJ single-pulse avalanche energy, validated under VDD = -50 V, L = 35 mH, and IAS = -3.6 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -200 V - Supports high-voltage DC bus isolation in industrial power supplies and battery management systems |
| RDS(on) | 1.5 Ω @ VGS = -10 V - Enables low conduction loss in 3–4 A load switching applications |
| Qg | 20 nC - Reduces gate driver power requirement and improves switching efficiency at 100–500 kHz |
| ID (continuous) | -3.6 A @ TC = 25 °C - Sustains steady-state current in compact PCB-mounted designs |
| EAS | 310 mJ - Absorbs inductive energy during fault events without failure in relay or solenoid drivers |
| tr/tf | 27 ns / 19 ns - Minimizes switching transition losses in high-frequency SMPS topologies |

Pinout & Package
DPAK (TO-252) surface-mount package with exposed drain pad for thermal conduction; 3-pin configuration optimized for automated assembly and PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (D) | Main current path output terminal | Connected to exposed metal tab - must be soldered to large copper pour for thermal management (RthJC = 3.0 °C/W) |
| Gate (G) | Control input for channel conduction | High-impedance node requiring <100 nA leakage handling; sensitive to ESD - needs series resistor for ringing suppression |
| Source (S) | Reference node for gate drive and current return | Common connection point for load return path; defines VGS reference - critical for high-side switch layout stability |
Key Features
| Feature | Design Value |
|---|---|
| Repetitive avalanche rated | Enables reliable operation under inductive turn-off stress without external snubbers in motor gate drives |
| Dynamic dV/dt rating | -5.0 V/ns immunity prevents false turn-on during high dv/dt transients in half-bridge configurations |
| Fast switching | 8.8 ns turn-on delay + 27 ns rise time allows >200 kHz PWM operation with minimal overlap loss |
| P-channel topology | Eliminates need for bootstrap circuitry in high-side switch applications like automotive window lift controllers |
| Surface-mount (DPAK) | Compatible with vapor-phase and infrared reflow; thermal pad enables 2.5 W dissipation on 1" FR-4 PCB |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel high-voltage power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRFR9120 | VDS = -200 V, RDS(on) = 2.7 Ω @ -10 V, Qg = 14 nC - higher on-resistance but lower gate charge | Lower current capability (-2.3 A @ 100 °C) suits lower-power auxiliary rails where thermal margin is constrained | Select when gate drive strength is limited and peak current ≤ 2.3 A; avoid for high-duty-cycle loads due to higher I²R loss |
| SiHFR9220 | Identical electrical specs and DPAK footprint; Pb-free/halogen-free construction per JEDEC J-STD-609 | No functional difference - direct material-compliance upgrade path for RoHS/REACH-constrained designs | Preferred for new designs requiring lead-free compliance; pin-to-pin and thermal drop-in replacement for IRFR9220 |
Compared with IRFR9220, IRFR9120 trades higher conduction loss for reduced gate drive demand, while SiHFR9220 offers identical performance with enhanced environmental compliance - both require no PCB layout changes but differ in thermal derating and regulatory qualification.

FAQ
What is the maximum continuous drain current rating for IRFR9220 at 100 °C case temperature?
The IRFR9220 supports -2.3 A continuous drain current at TC = 100 °C, derived from its linear derating factor of 0.33 W/°C and 42 W maximum power dissipation at 25 °C. This value reflects thermal limitations of the DPAK package under sustained high-temperature operation and must be verified against actual board layout and heatsinking.
Does IRFR9220 have an integrated body diode, and what are its key parameters?
Yes, the IRFR9220 includes an intrinsic body diode with -6.3 V forward voltage at -3.6 A and 150–300 ns reverse recovery time (trr). Its reverse recovery charge (Qrr) is 0.97–2.0 μC, and it supports -3.6 A continuous source-drain current - critical for freewheeling paths in H-bridge and buck converter topologies.
What is the gate-source threshold voltage range for IRFR9220, and how does it affect drive requirements?
The IRFR9220 has a gate-source threshold voltage (VGS(th)) range of -2.0 V to -4.0 V at ID = -250 μA. This indicates logic-level compatibility with -5 V or -10 V gate drive, but full enhancement requires VGS ≤ -10 V to achieve specified RDS(on) = 1.5 Ω - underscoring the need for adequate negative bias in high-side configurations.
Can IRFR9220 be used in avalanche mode, and what are the safe operating limits?
Yes, the IRFR9220 is repetitively avalanche rated with EAR = 4.2 mJ and IAR = -3.6 A, and single-pulse avalanche energy of 310 mJ. Safe operation requires pulse width limitation by junction temperature (TJ ≤ 150 °C), proper gate bias during avalanche, and adherence to test conditions: VDD = -50 V, L = 35 mH, Rg = 25 Ω.
What is the thermal resistance from junction to ambient for IRFR9220 in standard PCB mounting?
When mounted on a 1" square FR-4 PCB, the IRFR9220 exhibits RthJA = 50 °C/W - significantly lower than the 110 °C/W rating for free-air operation. This value assumes recommended minimum pad layout per Application Note 826 and enables 2.5 W power dissipation at TA = 25 °C before reaching TJ = 150 °C.
