7A, 700V N-CHANNEL
POWER MOSFET

DESCRIPTION
The UTC 7N70K-MTQ is a high voltage power 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) < 1.7Ω @ VGS = 10V, ID = 3.5A
* Fast switching capability
* Avalanche energy specified
* Improved dv/dt capability, high ruggedness
