ACPL-P343
ACPL-P343 is 4.0 Amp Output Current IGBT Gate Drive Optocoupler manufactured by Avago Technologies.
Description
The ACPL-P343/W343 contains an Al Ga As 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 1200 V / 200 A. For IGBTs with higher ratings, this optocoupler can be used to drive a discrete power stage which drives the IGBT gate. The ACPL-P343 and ACPL-W343 have the highest insulation voltage of VIORM = 891 Vpeak and VIORM = 1140 Vpeak respectively in the IEC/EN/DIN EN 60747-5-2.
