QFET
FQL40N50
500V N-Channel MOSFET
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 supply, power factor correction, motor drive and welding machine.

Features
40A, 500V, RDS(on) 0.11 VGS 10 V Low gate charge ( typical 155 nC) Low Crss ( typical 95 pF) Fast switching 100% avalanche tested Improved dv/dt capability
