800V N-Channel MOSFET

General Description

These N-Channel enhancement mode power field effecttransistors are produced using Fairchild’s proprietary,planar stripe, DMOS technology.This advanced technology has been especially tailored tominimize on-state resistance, provide superior switchingperformance, and withstand high energy pulse in theavalanche and commutation mode. These devices are wellsuited for high efficiency switch mode power supply.Features

•4.8A, 800V, RDS(on) = 2.6Ω @VGS = 10 V•Low gate charge ( typical 25 nC)•Low Crss ( typical 11 pF)•Fast switching•100% avalanche tested•Improved dv/dt capability

Absolute Maximum Ratings TC = 25°C unless otherwise noted
