FQD2N50B / FQU2N50B

500V N-Channel MOSFET

General Description

Features

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, electronic lamp ballast based on half

bridge.
