FQH35N40 Datasheet MOSFET

Manufacturer: Fairchild (now onsemi)

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, electronic lamp ballast based on half bridge.
