IRFP4321 N-Channel Power MOSFET

The IRFP4321 is an N-channel HEXFET power MOSFET designed for high efficiency and high reliability in demanding power systems. It is optimized for use in applications such as high-performance switch-mode power supplies (SMPS), uninterruptible power supplies (UPS), and high-speed power switching circuits. With its 150-Volt rating and exceptionally low on-state resistance, it minimizes conduction losses while providing a significant safety margin for voltage spikes. The device is fully avalanche rated, ensuring it can withstand extreme electrical stress during transient conditions. Its TO-247 package is a preferred choice for industrial applications where superior thermal dissipation is required, allowing the MOSFET to operate effectively under heavy continuous current loads.

Key Features:

Drain to source breakdown voltage (VDS) of 150 Volts.

Very low drain to source on-state resistance (RDSon) of 12 Milliohms.

High repetitive avalanche capability for improved reliability.

Fast switching speeds for high frequency power conversion.

Standard TO-247 package for low thermal resistance and high power handling.
