DESCRIPTION

The VOL3120 consists of an infrared light emitting diode

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 and solar

inverter 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 this optocoupler makes it ideally suited for directly driving

high power IGBTs with ratings up to 1000 V / 100 A. The low

profile and small footprint of the VOL3120 makes it an ideal

choice for applications where board space and component

height are at a premium, while still offering a high degree of

isolation performance.
