Overview
The FOD3150ASDV is a high-performance gate drive optocoupler produced by onsemi, designed to drive most 800V/20A IGBTs and MOSFETs. It is particularly suited for fast switching applications in motor control inverter systems and high-performance power systems. The device utilizes onsemi’s proprietary Optoplanar® coplanar packaging technology and optimized IC design to achieve high noise immunity, characterized by a minimum common mode rejection of 20kV/µs. It consists of a gallium aluminum arsenide (AlGaAs) light emitting diode optically coupled to an integrated circuit with a high-speed driver for a push-pull MOSFET output stage.
