onsemi FOD8383/4 High-Speed MOSFET/IGBT Optocouplers
onsemi FOD8383/4 High-Speed MOSFET/IGBT Gate Drive Optocouplers are 2.5A output current gate drive optocouplers that are capable of driving medium-power IGBT/MOSFETs. They are ideally suited for fast-switching driving of power IGBT and MOSFET used in motor-control inverter applications and high-performance power systems. The onsemi FOD8383/4 utilizes Optoplanar® coplanar packaging technology and optimized IC design to achieve reliable high-insulation voltage and high-noise immunity. Each device consists of an Aluminum Gallium Arsenide (AlGaAs) Light-Emitting Diode (LED) optically coupled to an integrated circuit with a high-speed driver for push-pull MOSFET output stage.
