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.
