Product Summary

The FQL40N50 is N-Channel enhancement mode power field effect transistors. This transistor is 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 valanche and commutation mode. These devices are well suited for high efficiency switch mode power supply, power factor correction, motor drive and welding machine.
