POWER MOSFET

DESCRIPTION
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.

FEATURES
* RDS(ON) < 10Ω @ VGS=10V, ID=0.5A
* Fast switching capability
* Avalanche energy specified
* Improved dv/dt capability, high ruggedness
