Description

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 and SiC(Silicon Carbide) MOSFETs used in inverter

or AC-DC/DC-DC converter applications. The high operat-

ing 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 optocou-

pler make it ideally suited for direct driving MOSFETs at

high frequency for high eciency conversion. The ACPL-

P346 and ACPL-W346 have the highest insulation voltage
