DESCRIPTION

The VOW3120 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

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

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

higher ratings, the VOW3120 can be used to drive a discrete

power stage which drives the IGBT gate.

The VOW3120 provides higher isolation for applications

operating at higher working voltages, and or higher pollution

degree criteria. Higher VIORM, VIOTM, creepage and

clearance distances, make the VOW3120 ideal for many

industrial control and power conversion applications.
