POWER MOSFET
DESCRIPTION
Power MOSFET
The UTC
2N70K
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
* R
DS(ON)
= 6.3Ω@V
GS
= 10V
* Ultra Low gate charge (typical 8.1nC)
* Low reverse transfer capacitance (C
RSS
= typical 5.0 pF)
* Fast switching capability
* Avalanche energy specified
* Improved dv/dt capability, high ruggedness
