- Helps to reduce equipment size and power consumption in test equipment applications
TOKYO — (BUSINESS WIRE) — September 25, 2019 — Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has started to ship “TLP3407SR,” a new voltage driven photorelay that delivers lower power dissipation and the industry’s smallest[1] mounting area.

TLP3407SR has a maximum limited LED current of 1mA at voltage input, a reduction to about one third of that of the earlier “TLP3407SRH.” With this, the new photorelay cuts maximum input power dissipation to 3.3mW[2], supporting lower power consumption by equipment such as probe cards, automatic semiconductor test equipment (ATE), semiconductor testers, and the boards of associated application.
When the input is a high voltage of 5V or more, the new photorelay can be driven by adding an external resistor in series, which allows designs with a maximum trigger LED reference current of 0.2mA. This approach realizes lower input current design in tester circuits.
The TLP3407SR’s small S-VSON4T[3] package has a mounting area of 2.9mm2, about 27% smaller than the current VSONR4[4] package and the industry’s smallest[1]. It supports size reductions in equipment like probe cards, or mounting of more photorelays.
Applications
- Probe cards
- Automatic semiconductor test equipment (ATE)
- Logic and memory testers, etc.
- Measuring instruments (Oscilloscope, data logger, etc.)
Features
- Low input power dissipation: 3.3mW (max) @3.3V, ILIM(LED)=1mA (max)
- Industry’s smallest[1] mounting area : 2.9mm2 (typ.)
- Two input voltages adopted for the control signal: DC3.3V (typ.) and DC5V (typ.)
