Toshiba Automotive Photocouplers & Photorelays

Toshiba automotive photocouplers and photorelays provide the isolation needed in battery management systems, inverters, and DC-DC converters, while offering the reliability and longevity needed in vehicle applications. 

All devices in the portfolio are AEC-Q101 qualified and photocouplers are offered with three types of outputs: IC Output Photocouplers can transmit at up to 20Mbps, Transistor Output Photocouplers are available with CTR up to 900 and 40V or 80V VCEO, and Photovoltaic Photocouplers offer a 12µA short circuit minimum and 7V open voltage minimum. Toshiba’s automotive photorelays are faster, smaller, quieter, and longer-lasting than mechanical relays, while providing cleaner and faster signaling.  

Toshiba’s automotive photocouplers and photorelays have a minimum isolation voltage rating of 3750VRMS and are housed in small SO-4 or SO-6 surface mount packages.
