FOD3120 Gate Drive Optocoupler

High Noise Immunity, 2.5A Output Current, Gate Drive Optocoupler

The FOD3120 (FOD3120-ND) is a 2.5A Output Current Gate Drive Optocoupler capable of driving most 800V/20A 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. It utilizes Fairchild’s patented 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.
