FQA44N08
80V N-Channel MOSFET
August 2000
QFETTM
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
suited for low voltage applications such as automotive, high
efficiency switching for DC/DC converters, and DC motor
control.
Features
• 49.8A, 80V, RDS(on) = 0.034Ω @VGS = 10 V
• Low gate charge ( typical 38 nC)
• Low Crss ( typical 90 pF)
• Fast switching
• 100% avalanche tested
• Improved dv/dt capability
• 175°C maximum junction temperature rating
