IRFW730B / IRFI730B

400V N-Channel MOSFET

General Description

Features

These N-Channel enhancement mode power field effect

transistors are produced using Fairchild’s proprietary,

planar, 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 supplies and

electronic lamp ballasts based on half bridge.
