New Voltage Driven Photorelays with Small Mounting Area to Reduce Semiconductor Tester Sizes
Toshiba Electronic Devices & Storage Corporation has launched three 4-Form-A voltage-driven photorelays “TLP3407SRA4,” “TLP3412SRHA4,” and “TLP3475SRHA4” that are housed in a newly-developed small S-VSON16T package and feature a typical mounting area of 12.5mm2. These devices are designed for applications such as semiconductor testers, which require mounting numerous relays on circuit boards that are limited in size.
By incorporating resistors at the input side, these devices are made to be driven by voltage without any need for external resistors which help to reduce space requirements on circuit boards, allowing more photorelays to be mounted. These devices feature a maximum operating temperature rating is 125°C, allowing use in high-temperature conditions and easily securing thermal-design margins.
