250V N-Channel MOSFET

FQP9N25C/FQPF9N25C

®

QFET

General Description

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

Features

• 8.8A, 250V, R

• Low gate charge ( typical 26.5 nC)

• Low Crss ( typical 45.5 pF)

•Fast switching

• 100% avalanche tested

• Improved dv/dt capability

= 0.43Ω @VGS = 10 V

DS(on)

suited for high efficiency switching DC/DC converters,
switch mode power supplies, DC-AC converters for
uninterrupted power supplies and motor controls.
