Product Summary
The IRF740B is an N-Channel enhancement mode power field effect transistor. It is 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. The IRF740B is well suited for high efficiency switch mode power supplies and electronic lamp ballasts based on half bridge.
