FQB7N10L / FQI7N10L
100V LOGIC N-Channel MOSFET
General Description
These N-Channel enhancement mode power field effect
transistors are produced using Fairchild’s proprietary,
planar stripe, DMOS technology.
This advanced technology is especially tailored to minimize
on-state
resistance,
provide
superior
switching
performance, and withstand high energy pulse in the
avalanche and commutation modes. These devices are
well suited for low voltage applications such as high
efficiency switching DC/DC converters, and DC motor
control.
