POWER MOSFET

DESCRIPTION
The UTC 3N70K-MK is a high voltage and high current 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 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) <4.2Ω @VGS = 10 V
* Low reverse transfer capacitance
* Fast switching capability
* Avalanche energy specified
* Improved dv/dt capability, high ruggedness
