Toshiba Electronic Devices & Storage Corporation launches four voltage driven photorelays: TLP3407SRB, TLP3412SRB, TLP3412SRHB and TLP3412SRLB. The devices are housed in a compact S VSON4T package and support a maximum operating temperature of 135°C.
The new models are designed for high temperature environments such as automotive semiconductor testers, probe cards and burn in equipment. As vehicle electrification and autonomous systems increase component density, semiconductor devices and test systems must operate reliably at higher temperatures.
Compared to earlier 125°C rated products, the new photorelays achieve higher temperature tolerance through optimized internal design. They are voltage driven with built in input resistors, eliminating the need for external resistors and helping reduce board space.
The small 1.45 × 2.0 mm package enables high density mounting where multiple photorelays are required within limited space. Toshiba states it will continue expanding its lineup to support high temperature equipment needs.
