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

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

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 @VIN=3.3V (TLP3407SRA)
