DESCRIPTION

The VOD3120A consists of a AlGaAs LED 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 VOD3120A is ideally suited for directly driving

IGBTs with ratings up to 1200 V / 100 A. For IGBTs with

higher ratings, the VOD3120A can be used to drive a

discrete power stage which drives the IGBT gate.
