DESCRIPTION
TO-220
The UTC 4N40 is an N-channel mode power MOSFET using
UTC’ s advanced technology to provide customers with planar stripe
and DMOS technology. This technology specializes in allowing a
minimum on-state resistance and superior switching performance. It
also can withstand high energy pulse in the avalanche and
commutation mode.
