ACPL-P345 and ACPL-W345
1.0 Amp Output Current Power & SiC MOSFET Gate Drive Optocoupler
with Rail-to-Rail Output Voltage in Stretched SO6
Data Sheet
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
of VIORM= 891Vpeak and VIORM= 1140Vpeak respectively in
the IEC/ EN/DIN EN 60747-5-5.
