The Infineon IRFP4321PBF is an N-channel power MOSFET designed for demanding applications such as motion control, high-efficiency synchronous rectification in SMPS, and uninterruptible power supplies.
Key electrical characteristics include a drain-source breakdown voltage (VDS) of 150V and a low typical on-resistance (RDS(on)) of 12mΩ at 33A with a 10V gate-source voltage. The continuous drain current (ID) is rated at 78A at 25°C case temperature.
This MOSFET features low gate charge for improved switching performance and an improved diode recovery time. It also boasts a 30V gate voltage rating for enhanced robustness. The device is housed in a TO-247AC package, suitable for through-hole mounting.
Applications benefit from its low RDS(on) which reduces conduction losses and low gate charge which improves switching efficiency. The improved diode recovery performance contributes to better switching and EMI performance.
