Overview
The FOD8343TR2V is a high-speed gate drive optocoupler produced by onsemi, designed to drive medium-power IGBTs and MOSFETs. This device is part of the FOD8343 series and is particularly suited for fast-switching applications in motor-control inverter systems and high-performance power systems. The FOD8343TR2V 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.
