FQB8N25 / FQI8N25 May 2000 QFET TM FQB8N25 / FQI8N25 250V N-Channel MOSFET General Description Features These N-Channel enhancement mode power field effect transistors are produced using Fairchild’s proprietary, planar stripe, 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, switch mode power supply. • • • • • • 8.0A, 250V, RDS(on) = 0.55Ω @VGS = 10 V Low gate charge ( typical 12 nC) Low Crss ( typical 11 pF) Fast switching 100% avalanche tested Improved dv/dt capability D D !
