Description

These N-Channel enhancement mode power field effect transistors of the IRFS720B are produced using Fairchild's proprietary, planar, DMOS technology.

This advanced technology of the IRFS720B 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.
