Optocoupler

The FOD8342 series is a 3.0 A output current gate drive optocoupler, capable of driving medium-power IGBT/MOSFETs. It is ideally suited for fast-switching driving of power IGBT and MOSFET used in motor-control inverter applications, and high-performance power systems.The FOD8342 series utilizes stretched body package to achieve 8 mm creepage and clearance distances (FOD8342T), and optimized IC design to achieve reliably high-insulation voltage and high-noise immunity.The FOD8342 series consists of an Aluminum Gallium Arsenide (AIGaAas) Light-Emitting Diode (LED) optically coupled to an integrated circuit with a high-speed driver for push-pull MOSFET output stage. The device is housed in a stretched body, 6-pin, small outline plastic package.
