UF450
14A, 500V N-CHANNEL
POWER MOSFET
DESCRIPTION
Power MOSFET
The
UF450
uses advanced UTC technology to provide
excellent R
DS (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
* R
DS(ON)
< 0.4Ω@V
GS
= 10V
* Ultra Low Gate Charge (Max. 150nC )
* Low Reverse Transfer Capacitance ( C
RSS
= Typical 340pF )
* Fast Switching Capability
* Avalanche Energy Specified
* Improved dv/dt Capability
