Introduction

The ACPL-P346/W346 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, GaN (Gallium Nitride) and SiC(Silicon Carbide) MOSFETs used in inverter or AC-DC/DC-DC converter 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 MOSFETs at high frequency for high efficiency conversion. The ACPL-P346 and ACPL-W346 have the highest insulation voltage of V_IORM = 891 V_peak and V_ORM = 1140 V_peak respectively in the IEC/EN/DIN EN 60747-5-5.
