DESCRIPTION
The UTC 4N65K-MK is a high voltage power MOSFET
designed to have better characteristics, such as fast switching
time, low gate charge, low on-state resistance and have a high
rugged avalanche characteristic. This power MOSFET is usually
used in high speed switching applications including power supplies,
PWM motor controls, high efficient DC to DC converters and bridge
circuits.

