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 switch mode power supplies,
Features
• 24A, 500V, R
• Low gate charge ( typical 90 nC)
• Low Crss ( typical 55 pF)
• Fast switching
• 100% avalanche tested
• Improved dv/dt capability
• Fast recovery body diode ( max, 250ns )
= 0.2Ω @VGS = 10 V
