Toshiba’s New Photorelays Contribute to Equipment Downsizing by Reducing Mounting Density

Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched three photorelays: “TLP3407SRA ,” “TLP3475SRHA ” and “TLP3412SRHA ,” that are the industry-smallest[1] voltage driven photorelays with an extended operating temperature rating of 125°C.

This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20200826005815/en/

Raising the maximum operating temperature rating from 110°C to 125°C allows the photorelays to be mounted in high temperature areas, and makes it easier to secure required temperature design margins for equipment. The S-VSON4T package has the industry-smallest[1] mounting area of 2.9mm² .This will contribute to reducing PCB size or to increasing the number of photorelays in an existing layout in applications such as semiconductor testers, probe cards and other devices.

Applications

  • Semiconductor testers (memory, SoC and LSI, etc.)
  • Probe cards
  • Burn-in equipment
  • Measuring instruments (oscilloscope, data logger, etc.)

Features

  • S-VSON4T, the industry’s first[1] packaging with a minimal mounting area and maximum operating temperature of 125°C: Mounting area 2.9mm2 (typ.)
  • Low input power consumption drive: 3.3mW[2] (max) @VIN =3.3V (TLP3407SRA)
