Description
The FOD3120 is a 2.5 A Output Current Gate Drive Optocoupler,
capable of driving most medium power IGBT/MOSFET. It is ideally
suited for fast switching driving of power IGBT and MOSFETs used
in motor control inverter applications, and high performance power
system.
I t u t i l i z e s o n s e m i ’s c o p l a n a r p a c k a g i n g t e c h n o l o g y,
OPTOPLANAR®, and optimized IC design to achieve high noise
immunity, characterized by high common mode rejection.
It consists of a gallium aluminum arsenide (AlGaAs) light emitting
diode optically coupled to an integrated circuit with a high −speed
driver for push−pull MOSFET output stage.
