with Active Miller Clamp, Rail-to-Rail Output Voltage

and UVLO in Stretched SO8

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-H342/ACPL-K342 contains an AlGaAs LED,

which is optically coupled to an integrated circuit with a

power output stage. This optocoupler is 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 high peak output

current supplied by this optocoupler make it ideally suited

for direct driving IGBT with ratings up to 1200V/150A. For

IGBTs with higher ratings, the ACPL-H342/ACPL-K342 can

be used to drive a discrete power stage which drives the

IGBT gate.The ACPL-H342 and ACPL-K342 have the highest

respectively in the IEC/ EN/DIN EN 60747-5-5.
