ACPL-P341 and ACPL-W341 3.0 Amp Output Current IGBT Gate Drive Optocoupler with Rail-to-Rail Output
Voltage in Stretched SO6
Data Sheet
Description
The ACPL-P341/W341 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 1200 V / 100 A. For IGBTs with higher ratings, this optocoupler can be used to drive a discrete power stage which drives the IGBT gate. The ACPL-P341 and ACPL-W341 have the highest insulation
voltage of VIORM = 891Vpeak and VIORM = 1140 Vpeak respectively in the IEC/ EN/DIN EN 60747-5-2.
