The HCPL-3120 contains a GaAsP LED while the HCPLJ312 and the HCNW3120 contain an AlGaAs 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 1200 V/100 A. For IGBTs with higher ratings, the HCPL-3120 series can be used to drive a discrete power stage which drives the IGBT gate. The HCNW3120 has the highest insulation voltage of VIORM=1414Vpeak in the IEC/EN/DIN EN 60747-5-5. The HCPL-J312 has an insulation voltage of VIORM=1230Vpeak and the VIORM=630Vpeak is also
available with the HCPL-3120 (Option060).
