Description
Features
The ACPL-H342/ACPL-K342 contains an AlGaAs LED, • 2.5 A Maximum Peak Output Current
which is optically coupled to an integrated circuit with a
power output stage. This optocoupler is ideally suited for
driving power IGBTs and MOSFETs used in motor control
inverter 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 IGBT with ratings up to 1200V/150A. For
IGBTs with higher ratings, the ACPL-H342/ACPL-K342 can
be used to drive a discrete power stage which drives the
