General Description

These P-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

Features

• -7.3A, -200V, R

• Low gate charge ( typical 31 nC)

• Low Crss ( typical 30 pF)

• Fast switching

• 100% avalanche tested

• Improved dv/dt capability

= 0.47Ω @VGS = -10 V
