Description
Features
The ACPL-H342/ACPL-K342 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 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
IGBT gate.The ACPL-H342 and ACPL-K342 have the highest
insulation voltage of VIORM = 891Vpeak and 1140Vpeak
respectively in the IEC/ EN/DIN EN 60747-5-5.

Notes:
1. All Avago data sheets report the creepage and clearance inherent to the optocoupler component itself. These dimensions are needed as a
starting point for the equipment designer when determining the circuit insulation requirements. However, once mounted on a printed circuit
board, minimum creepage and clearance requirements must be met as specified for individual equipment standards. For creepage, the shortest
distance path along the surface of a printed circuit board between the solder fillets of the input and output leads must be considered. There are
recommended techniques such as grooves and ribs which may be used on a printed circuit board to achieve desired creepage and clearances.
Creepage and clearance distances will also change depending on factors such as pollution degree and insulation level.
