The new photorelays deliver a maximum operating temperature rating of 135°C for equipment that operates at high temperatures. Volume shipments start today. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260224680610/en/ Advances in electrification and autonomous driving now require high-density packaging of electronic components in automotive equipment. This has raised the temperatures at which automotive semiconductors operate, and testing under similar conditions is necessary to evaluate reliability; testers, burn-in equipment, probe cards, and other devices for automotive semiconductors must be able to operate at high temperatures, as must the photorelays used in them. The maximum operating temperature of Toshiba’s new products have been pushed from the 125°C of current products\[1\] to 135°C by optimizing the design of built-in elements. In addition, because they are voltage-driven type photorelays with built-in resistors on the input side, no external resistor is required, reducing space requirements on mounting boards. They are also housed in a small package, the S-VSON4T, which is 1.45 × 2.0 mm (typ.). The combination of these factors makes the new photorelays suitable for application in automotive semiconductor testers, probe cards, and burn-in equipment, where multiple photorelays need to be mounted within a limited board space, and reliable high-temperature operation is required. Toshiba will continue to offer a lineup of products that support high-temperature operation in equipment.
