General Description
These N-Channel enhancement mode power field effect
FQB44N10 / FQI44N10
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 audio amplifier,
high efficiency switching DC/DC converters, and DC motor
control.
