Optocoupler Logic-Out Push-Pull DC-IN 1-CH 8-Pin PDIP Tube
The HCPL-3120 contains a GaAsP LED while the HCPLJ312and the HCNW3120 contain an AlGaAs LED. The LEDis optically coupled to an integrated circuit with a poweroutput stage. These optocouplers are ideally suited fordriving power IGBTs and MOSFETs used in motor controlinverter applications. The high operating voltage rangeof the output stage provides the drive voltages requiredby gate controlled devices. The voltage and currentsupplied by these optocouplers make them ideallysuited for directly driving IGBTs with ratings up to 1200V/100 A. For IGBTs with higher ratings, the HCPL-3120series can be used to drive a discrete power stage whichdrives the IGBT gate. The HCNW3120 has the highest insulationvoltage of VIORM=1414Vpeak in the IEC/EN/DINEN 60747-5-5. The HCPL-J312 has an insulation voltageof VIORM=1230Vpeak and the VIORM=630Vpeak is alsoavailable with the HCPL-3120 (Option060).
