The FOD3125 is a 2.5 A Output Current Gate Drive Optocoupler, capable of driving most medium power IGBT/MOSFET at high temperature up to 125°C. 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 ON Semiconductor’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 aluminium arsenide (AlGaAs) light emitting diode optically coupled to an integrated circuit with a high-speed driver for push-pull MOSFET output stage.

Extended Industrial Temperate Range, -40°C to 125°C
High Noise Immunity Characterized by 35kV/μs Minimum Common Mode Rejection
2.5 A Peak Output Current Driving Capability for Most 1200 V/20 A IGBT
