FQB4N90 Datasheet 900v N-channel MOSFET

Manufacturer: Fairchild (now onsemi)

Overview: FQB4N90 / FQI4N90 October 2001 QFET FQB4N90 / FQI4N90 900V N-Channel.

General Description

These N-Channel enhancement mode power field effect transistors are produced using Fairchild’s proprietary, planar stripe, DMOS technology.

This advanced technology has been especially tailored to minimize on-state resistance, provide superior switching performance, and withstand high energy pulse in the avalanche and commutation mode.

These devices are well suited for high efficiency switch mode power supplies.
