Description

The ACPL-P345/W345 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 efficiency conversion. The ACPL-

P345 and ACPL-W345 have the highest insulation voltage

the IEC/ EN/DIN EN 60747-5-5.
