QFETTM

FQT3P20

200V P-Channel MOSFET

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

suited for high efficiency switching DC/DC converters.

Features

• -0.67A, -200V, RDS(on) = 2.7Ω @VGS = 10 V

• Low gate charge ( typical 6.0 nC)

• Low Crss ( typical 7.5 pF)

• Fast switching

• Improved dv/dt capability

Absolute Maximum Ratings TC = 25°C unless otherwise noted
