ACPL-H312 and ACPL-K312

2.5 Amp Output Current IGBT Gate Driver Optocoupler

Data Sheet

CAUTION: It is advised that normal static precautions be taken in handling and assembly

of this component to prevent damage and/or degradation which may be induced by ESD.

Description

The ACPL-H312/K312 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 sup-

plied 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-H312 /K312 series can

be used to drive a discrete power stage which drives the

IGBT gate. The ACPL-H312 has an insulation voltage of
