DESCRIPTION
The UTC 2N70-C is a high voltage MOSFET designed to have
better characteristics, such as fast switching time, low gate charge,
low on-state resistance and 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) < 6.3Ω @ VGS = 10V, ID =1A
* Fast switching capability
* Avalanche energy specified
* Improved dv/dt capability, high ruggedness
