Description
The ACPL-P347/W347 contains an AlGaAs LED, which is
optically coupled to an integrated circuit with a power output
stage. This optocoupler is ideally suited for driving SiC/GaN
(Silicon Carbide/Gallium Nitride) MOSFETs and IGBTs used in
power conversion 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 SiC/GaN MOSFET and IGBT with ratings up to
1200V/50A.
