Toshiba’s new high-voltage automotive photorelay detects relay sticking and ground faults

Toshiba Electronic Devices & Storage has launched a new photorelay that’s designed for high-voltage automotive batteries, battery voltage monitoring, and the detection of mechanical relay sticking and ground faults.

The new TLX9160T is an AEC-Q101-qualified photorelay that’s composed of a SO16L-T package, and features high-voltage MOSFETs and an avalanche current rating of 0.6 mA in IAV. The package is made of a resin from the IEC 60664-1 international standard material group I and has a Comparative Tracking Index over 600 and four fewer pins than the company’s existing SO16L package. High-voltage MOSFETs facilitate a high-output withstand voltage of 1,500 V.

The normally open (NO) 1-Form-A photorelay can accommodate battery voltage up to 1,000 V. It’s available now.
