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.

MARKING DIAGRAM
It 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.
