39A, 200V N-CHANNEL
POWER MOSFET
DESCRIPTION
The UTC
39N20
is a N-channel mode power MOSFET using
UTC’s advanced technology to provide customers with a minimum
on-state resistance, low gate charge and high switching speed.
The UTC
39N20
is suitable for high voltage synchronous rectifier
and DC/DC converters, etc.
