Toshiba Launches Voltage-Driven Photorelay in One of Industry’s Smallest Package Types

Toshiba Launches 4-Form-A Voltage Driven Photorelay in One of the Industry’s Smallest Package Types[1] to Further Reduce the Size of Semiconductor Testers

Shanghai, China, December 16, 2021 – Toshiba Electronic Devices & Storage Corporation (“Toshiba”) today announced the launch of three 4-Form-A voltage-driven photorelays in one of the industry’s smallest package types[1] – the TLP3407SRA4, TLP3412SRHA4 and TLP3475SRHA4. Mass shipments of the three devices began today.

The new products are Toshiba 's first ever four-channel normally open photorelays . They are packaged in the newly developed small S-VSON16T package, with a typical mounting area of ​​only 12.5mm2, one of the smallest package types in the industry. And because resistors are built into the input side, these products can be driven by voltage without any external resistors. These features help reduce the need for board space, allowing more photorelays to be installed.

The new photorelays are ideal for applications such as semiconductor testers where a large number of relays need to be mounted on a circuit board where space is limited.

The new product has a maximum rated operating temperature of 125°C, making it suitable for high-temperature environments and making it easier to ensure thermal design margin.

application:

-Semiconductor testers (probe cards and test heads for memory, SoC, LSI, etc.)

-Aging equipment

- Measuring instruments (oscilloscopes, data loggers, etc.)

characteristic:

-Using S-VSON16T package, one of the smallest package types in the industry, 4-Form-A contacts

- Voltage drive type with integrated input resistor, no external resistor required (input voltage: 3.3V system or 5V system)

- High rated operating temperature: Topr maximum = 125°C
