Product Summary

The A3120 is a 2.5 Amp Output Current IGBT Gate Drive Optocoupler. It contains a GaAsP LED. The A3120 can be used to drive a discrete power stage which drives the IGBT gate. It has the highest insulation voltage of VIORM = 1414 Vpeak in the IEC/EN/DIN EN 60747-5-2. The A3120 has an insulation voltage of VIORM = 891 Vpeak and the VIORM = 630 Vpeak is also available with the HCPL-3120 (Option 060). The applications of the device include IGBT/MOSFET gate drive, AC/Brushless DC motor drives, Industrial inverters and Switch mode power supplies.
