Toshiba Electronic Devices & Storage Corporation has introduced “TLP3407SR,” a new voltage driven photorelay that delivers lower power dissipation within the industry’s smallest mounting area. TLP3407SR has a maximum limited LED current of 1mA at voltage input which is a reduction to about one third of that of the earlier “TLP3407SRH”. So, the new photo relay cuts maximum input power dissipation to 3.3mW.

 

The new photorelay can be driven by adding an external resistor in series if the input voltage is 5V or more, This helps the designs with a maximum trigger LED reference current of 0.2mA. This approach realizes the lower input current design in tester circuits. The TLP340SR’s small S-VSON4T package has a mounting area of 2.9mm2 , which is 27% smaller than the current VSONRa package and all other smallest packages in the industry. It helps in size reduction and lower power consumption in test equipment like probe cards, or mounting of more photo relays.

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.)
