Shipment of the new photorelays, which can be used in applications including semiconductor testers, probe cards and replacements for mechanical relays, starts today.

Use of photorelays at higher temperatures is increasing in various applications, including semiconductor testers. To meet the demand, the operating temperature of the 12 products in the 2.45mm(L)×1.45mm(W)×1.3mm(H) small package “VSON4 Series” has been extended from 85 degrees to 110 degrees Celsius, for a total range of -40 to 110 degrees Celsius. Designers can take advantage of the extended features to design sets with an expanded design margin.
