2.5A Gate Drive Optocoupler in Stretched SO8

Currently Viewing:

The ACPL-K312 gate drive optocoupler contains a GaAsP 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 ACPL-K312 can be used to drive a discrete power stage which drives the IGBT gate. The ACPL-K312 has an insulation voltage of VIORM = 1140 Vpeak (Option 060).
