Overview
The FOD8343TR2 is a high-speed gate drive optocoupler produced by ON Semiconductor. It is designed to drive medium-power IGBTs and MOSFETs, making it ideal for fast-switching applications in motor-control inverters and high-performance power systems. The device features an Aluminum Gallium Arsenide (AlGaAs) Light-Emitting Diode (LED) optically coupled to an integrated circuit with a high-speed driver for a push-pull MOSFET output stage. It is housed in a stretched body, 6-pin, small outline plastic package, which enhances creepage and clearance distances for reliable high-voltage insulation.
