描述 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 utilizes onsemi’s coplanar packaging technology,

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.
