1.0 Amp Output Current Power & SiC MOSFET Gate Drive Optocoupler with Rail-to-Rail Output Voltage in Stretched SO6

Currently Viewing:

The ACPL-P345 is a high-speed 1A gate drive optocoupler that 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 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 has the highest insulation voltage of VIORM= 891Vpeak in the IEC/ EN/DIN EN 60747-5-5 and is UL1577 recognized with 3750 VRMS for 1 minute.
