Wide Operating Temperature 2.5Amp Output Current IGBT Gate Drive R2CouplerTM

Currently Viewing:

The ACPL-312U gate drive optocoupler  contains an AIGaAs LED. The LED is optically coupled to an integrated circuit with a power output stage. This wide operating temperature optocoupler is ideally suited for driving power IGBTs and MOSFETs used in wide operating temperature motor control inverter and DC-DC converters applications. The high operating voltage range of the output stage provides the drive voltages required by gate controlled devices. The voltage and current supplied by these optocouplers make them ideally suited for directly driving IGBTs with ratings up to 1200 V/ 100 A. For IGBTs with higher ratings, the ACPL-312U series can be used to drive a discrete power stage which drives the IGBT gate.
