ACPL-P343 and ACPL-W343
4.0 Amp Output Current IGBT Gate Drive Optocoupler
with Rail-to-Rail Output Voltage in Stretched SO6
Data Sheet
Description
The ACPL-P343/W343 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 1200 V
/ 200 A. For IGBTs with higher ratings, this optocoupler
can be used to drive a discrete power stage which drives
the IGBT gate. The ACPL-P343 and ACPL-W343 have the
highest insulation voltage of V_IORM = 891 V_peak and V_IORM
= 1140 V_peak respectively in the IEC/EN/DIN EN 60747-5-2.
