The ACPL-K342/ACPL-H342 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 insulation voltage of VIORM = 891Vpeak and 1140Vpeak respectively in the IEC/ EN/DIN EN 60747-5-5.
