This document introduces the HUF75332G3, HUF75332P3, and HUF75332S3S N-Channel UltraFET power MOSFETs manufactured by Fairchild Semiconductor Corporation. These devices are made using the innovative UltraFET process and offer the lowest possible on-resistance and outstanding performance. They are capable of withstanding high energy in the avalanche mode and have very low reverse recovery time and stored charge. They are designed for applications where power efficiency is important, such as switching regulators, switching converters, motor drivers, relay drivers, low-voltage bus switches, and power management in portable and battery-operated products.
