HCNW3120-500E Integrated Circuit Chip 2.5A Output Current IGBT Gate Drive Optocoupler

HCNW3120-500E contains a GaAsP LED while the HCPL-J312 and the HCNW3120-500E contain an AIGaAs LED. The LED is optically coupled to an integrated circuit with a power output stage. These optocouplers are 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 these optocouplers make them ideally suited for directly driving IGBTs with ratings up to 1200V/100A. For IGBTs with higher ratings, the HCPL-3120 series can be used to drive a discrete power stage, which drives the IGBT gate.
