POWER MOSFET

DESCRIPTION
The UTC 1N70K-TA 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.
