Description

These N-Channel enhancement mode power field effect transistors of the IRF740B are produced using Fairchild's proprietary, planar, DMOS technology.

This advanced technology of the IRF740B 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.
