A3120 IGBT Gate Drive Optocoupler

The HCPL-3120 consists of a GaAsP LED optically coupled to an integrated circuit with a power output stage.

This opto-coupler is ideally suited for driving power IGBTs and MOSFETs used in motor control inverter applications. The high operating voltage range of the output stage provides the drive voltages required by gate controlled devices. The voltage and current supplied by A3120 IGBT optocoupler makes it ideally suited for directly driving IGBTs with ratings up to 1200 V/100 A. For IGBTs with higher ratings, the HCPL-3120 can be used to drive a discrete power stage which drives the IGBT gate.
