IRFM224B 250V N-Channel MOSFET General Description Features 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 converters and switch mode power supplies. • • • • • 0.92A, 250V, RDS(on) = 1.1Ω @VGS = 10 V Low gate charge ( typical 13.5 nC) Low Crss ( typical 9.5 pF) Fast switching Improved dv/dt capability D !
