The IRFI4321PBF is an N-Channel enhancement-mode power MOSFET manufactured by Infineon Technologies, part of the HEXFET family. It is designed for power switching applications requiring high efficiency and robustness. The device is rated for a 150V drain-to-source breakdown voltage, 34A continuous drain current at 25°C case temperature (21A at 100°C), and 140A pulsed drain current. Maximum power dissipation is 46W at 25°C case temperature.
Electrical characteristics include a maximum static drain-to-source on-resistance of 16mOhm at VGS=10V and ID=20A, with a typical value of 12.2mOhm. Gate threshold voltage ranges from 3V to 5V. The device features a maximum gate charge of 110nC at VGS=10V and input capacitance of 4440pF at VDS=50V, supporting efficient high-frequency switching. It also has a single-pulse avalanche energy rating of 170mJ.
The IRFI4321PBF is available in a TO-220 Full-Pak (TO-220AB Full-Pak) through-hole package, which offers isolated mounting. Operating junction temperature range is -55°C to 150°C, with junction-to-case thermal resistance of 2.73°C/W. It is intended for applications such as motion control, synchronous rectification in switched-mode power supplies, uninterruptible power supplies, and hard-switched high-frequency circuits.
