Toshiba TLP3407SRA4, TLP3412SRHA4 and TLP3475SRHA4 4-Form-A photorelays

Toshiba Electronic Devices & Storage has launched three 4-Form-A voltage-driven photorelays: the TLP3407SRA4, TLP3412SRHA4 and TLP3475SRHA4. They have a mounting area of just 12.5 mm², which is said to be one of the smallest in the industry.

The photorelays are Toshiba’s first-ever four-circuit, 4-Form-A relays. By incorporating resistors at the input side, the products are made to be driven by voltage without any need for external resistors. These features help to reduce space requirements on circuit boards, allowing more photorelays to be mounted.

The products are suitable for applications such as semiconductor testers, which require mounting of numerous relays on circuit boards that are limited in size, as well as burn-in equipment and measuring instruments. They have a maximum operating temperature of 125°C, allowing use in high-temperature conditions and easily securing thermal-design margins.
