Toshiba Releases High Voltage 1500V Automotive Photorelay

New device is suited for high voltage automotive batteries.

Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched “TLX9160T,” a normally open (NO) 1-Form-A photorelay suited for high voltage automotive batteries. Housed in an SO16L-T package, the new device is Toshiba’s first to feature a high output withstand voltage of 1500V (min). Volume shipments start today.

Incorporation of high voltage MOSFETs in the new device achieves an output withstand voltage of 1500V (min). An SO16L-T package made of a resin in the IEC 60664-1 international standard material group I, which has CTI exceeding 600 and four fewer pins (pins from 11 to 14 are removed from existing SO16L package), realizes creepage of 5mm or more at the device’s detector. This ensures support for 1000V supply voltage under IEC 60664‐1, suiting the photorelay for high voltage automotive applications with a battery voltage of up to 1000V.
