QFET
FQA90N08
80V 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 a high energy pulse in the avalanche and commutation modes. These devices are well suited for low voltage applications such as automotive, high efficiency switching for DC/DC converters, and DC motor control.

Features
90A, 80V, RDS(on) 0.016 VGS 10 V Low gate charge ( typical 84 nC) Low Crss ( typical 200 pF) Fast switching 100% avalanche tested Improved dv/dt capability 175 C maximum junction temperature rating
