IRFW634B / IRFI634B
250V N-Channel MOSFET
General Description
These N-Channel enhancement mode power field effect
transistors are 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. These devices are well suited for high efficiency switching DC/DC converter and switch mode power supplies.
Features
8.1A, 250V, RDS(on) = 0.45Ω @VGS = 10 V Low gate charge ( typical 29 nC) Low Crss ( typical 20 pF) Fast switching 100% avalanche tested Improved dv/dt capability
