FOD8333 Output Current IGBT Drive Optocouplers onsemi's FOD8333 2.5A Output Current IGBT Drive Optocouplers are an advanced 2.5A output current IGBT drive optocoupler capable of driving medium-power IGBTs with ratings up to 1200V and 150A. They are suited for fast-switching driving of power IGBTs and MOSFETs in motor-control inverter applications and high-performance power systems. The onsemi FOD8333 offers protection features necessary for preventing fault conditions that lead to destructive thermal runaway of IGBTs.
