Toshiba Launches Voltage Driven Photorelay in Industry’s Smallest Package with Reduced Input Power Dissipation
Helps to reduce equipment size and power consumption in test equipment applications
TOKYO--(Business Wire / Korea Newswire) September 26, 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 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, 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 package has a mounting area of 2.9mm2, about 27% smaller than the current VSONR4 package and the industry’s smallest. It supports size reductions in equipment like probe cards, or mounting of more photorelays.
· Probe cards
· Automatic semiconductor test equipment (ATE)
· Logic and memory testers, etc.
· Measuring instruments (Oscilloscope, data logger, etc.)
· Low input power dissipation: 3.3mW (max) @3.3V, ILIM(LED)=1mA (max)
· Industry’s smallest mounting area : 2.9mm2 (typ.)
· Two input voltages adopted for the control signal: DC3.3V (typ.) and DC5V (typ.)
