1.5 Amp Output Current IGBT Gate Drive Optocoupler

Currently Viewing:

The HCPL-T250 gate drive optocoupler contains GaAs LED. The LED is 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 voltage and current supplied by this optocoupler makes it ideally suited for directly driving IGBTs with ratings up to 1200 V/25 A. For IGBTs with higher ratings, the HCPL-T250 can be used to drive a discrete power stage which drives the IGBT gate.
