Optocoupler features 'industry leading' fast switching
Renesas Electronics has announced the availability of a drive optocoupler with 'industry leading' fast switching and integrated insulated gate bipolar transistor (igbt) protection function.
The PS9402 optocoupler comprises a gallium aluminium arsenide (GaAlAs) LED as the light emitting element, a photodetector IC and an igbt protection circuit. It has been designed to drive igbts used in inverter devices for purposes such as motor control. According to Renesas, the use of the new optocoupler eases the design of igbt peripheral circuits and enables igbt direct drive up to the 1200V and 100A class.
