Avago Technologies ACPL-x345 SiC MOSFET Gate Drive Optocouplers

Avago Technologies ACPL-x345 SiC MOSFET Gate Drive Optocouplers

Avago Technologies ACPL-x345 SiC MOSFET Gate Drive Optocouplers each contain 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 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-P345 and ACPL-W345 have the highest insulation voltage of VIORM = 891Vpeak and VIORM = 1140Vpeak respectively in the IEC/ EN/DIN EN 60747-5-5.
