Introduction

The FOD8343 series is a 4.0 A maximum peak 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 FOD8343 series utilizes stretched body package to achieve 8 mm creepage and clearance distances (FOD8343T), and optimized IC design to achieve reliably high-insulation voltage and high-noise immunity. The FOD8343 series 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. The device is housed in a stretched body, 6-pin, small outline, plastic package.
