Product Summary

The FQA40N25 is an N-channel enhancement mode power field effect transisitor produced using Fairchild’s proprietary, planar stripe, DMOS technology. The 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 device is well suited for high effciency switching DC/DC converters, switch mode power supply.
