POWER MOSFET
DESCRIPTION
Preliminary
Power MOSFET
The UTC
1N50-KW
is a high voltage MOSFET and is
designed to have better characteristics, such as fast switching
time, low gate charge, low on-state resistance and have a high
rugged avalanche characteristics. This power MOSFET is usually
used at high speed switching applications in power supplies,
PWM motor controls, high efficient DC to DC converters and
bridge circuits.
