The FOD3120T is a 2.5A output current gate drive optocoupler, capable of driving most 800V/20A IGBT/MOSFET. It is suited for fast switching driving of power IGBT and MOSFETs used in motor control inverter applications, and high performance power system. It utilizes Fairchild’s proprietary 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 (LED) optically coupled to an integrated circuit with a high-speed driver for push-pull MOSFET output stage.
