RDS(on) = 0.140Ω ( Typ.)@ VGS = 10V, ID = 14A
Low Gate Charge ( Typ. 80nC)
Low Crss ( Typ. 38pF)
These N-Channel enhancement mode power field effect
transistors are produced using Fairchild’s proprietary, planar
stripe, DMOS technology.
This advance 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 device are well suited for high
efficient switched mode power supplies and active power factor
correction.
