It supports fast switching, repetitive avalanche operation, and is optimized for high-voltage DC-DC converters and industrial motor control.
For engineers reviewing the IRFU9220PBF datasheet, IRFU9220PBF pinout, IRFU9220PBF application, or IRFU9220PBF equivalent, this page delivers verified electrical parameters, thermal derating behavior, gate charge profile, body diode recovery characteristics, and direct-mount PCB thermal performance data - all confirmed from Vishay's official S21-0373-Rev. F specification.
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 -200 V VDS rating and -3.6 A ID support high-side switching in off-line SMPS and battery-powered HV systems.
The IRFU9220PBF features a built-in body diode with trr = 150–300 ns and Qrr = 0.97–2.0 μC, enabling efficient synchronous rectification or freewheeling in flyback and half-bridge topologies. Its dV/dt immunity of -5.0 V/ns ensures robust operation under fast transient conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel high-voltage MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRFR9220PbF | DPAK (TO-252) surface-mount package; identical electrical specs and thermal RthJC = 3.0 °C/W | Requires reflow-compatible layout; better suited for automated assembly and higher power density boards | Select when PCB space is constrained and SMT process is available |

FAQ
What is the maximum continuous drain current for IRFU9220PBF at 100 °C case temperature?
The IRFU9220PBF supports -2.3 A continuous drain current at TC = 100 °C, per its Absolute Maximum Ratings table. This derated value reflects thermal limitations of the IPAK package mounted on standard PCB; actual current capability depends on heatsinking and ambient conditions. Designers must verify junction temperature using RthJC = 3.0 °C/W and ensure TJ ≤ 150 °C under worst-case load.
Does IRFU9220PBF have avalanche capability, and how is it specified?
Yes, IRFU9220PBF is repetitively avalanche rated: it supports IAR = -3.6 A and EAR = 4.2 mJ under defined pulse conditions (TJ ≤ 150 °C, pulse width limited by max junction temperature). Single-pulse avalanche energy is rated at 310 mJ. These values are measured per Vishay's unclamped inductive test circuit (Fig. 12a) and enable reliable operation in inductive load switching without external snubbers.
What is the gate threshold voltage range for IRFU9220PBF, and how does it affect drive requirements?
The IRFU9220PBF has a gate-source threshold voltage VGS(th) of -2.0 V to -4.0 V at ID = -250 μA. This range ensures reliable turn-on with gate drives ≥ -5 V, making it compatible with standard logic-level controllers. For full enhancement and minimal RDS(on), -10 V is recommended - delivering 1.5 Ω on-resistance versus >10 Ω at -5 V due to transconductance roll-off.
How does the body diode performance of IRFU9220PBF impact its use in synchronous rectification?
The IRFU9220PBF body diode exhibits trr = 150–300 ns and Qrr = 0.97–2.0 μC at TJ = 25 °C, with VSD = -6.3 V at IS = -3.6 A. While not optimized for ultra-fast synchronous rectification, these parameters allow acceptable efficiency in medium-frequency flyback or forward converters where external Schottky diodes are impractical. Designers should evaluate reverse recovery loss against switching frequency and load current.
What is the thermal resistance from junction to ambient for IRFU9220PBF when mounted on a 1" square FR-4 PCB?
When mounted on a 1" square FR-4 or G-10 PCB, the IRFU9220PBF has RthJA = 50 °C/W, enabling 2.5 W maximum power dissipation at TA = 25 °C. This value assumes standard copper layout per Vishay Application Note 826; doubling copper area reduces RthJA by ~15–20 %. Junction temperature must be calculated using PD × RthJA + TA ≤ 150 °C.
