UF450
Power MOSFET
14A, 500V N-CHANNEL
POWER MOSFET

DESCRIPTION
The UF450 uses advanced UTC technology to provide
excellent RDS (ON), low gate charge and operation with low gate
voltages. This device is suitable for use as a load switch, in PWM
applications, motor controls, inverters, choppers, audio amplifiers
and high energy pulse circuits.

FEATURES
* RDS(ON) < 0.4Ω@VGS = 10V
* Ultra Low Gate Charge (Max. 150nC )
* Low Reverse Transfer Capacitance ( CRSS = Typical 340pF )
* Fast Switching Capability
* Avalanche Energy Specified
* Improved dv/dt Capability
