Toshiba Electronics Europe has released a new voltage driven photorelay designed in a tiny S-VSON4T package, with reduced input power dissipation.

Designated as TLP3407SR, the device features a maximum LED current of just 1mA at the input, which represents a reduction to approximately 33% of that of its predecessor. This allows the product to offer a maximum input power dissipation of 3.3 mW. For use with higher voltages of 5 V or more, the new device can be powered by adding an external resistor in series, allowing designers to implement a maximum trigger LED current of 0.2 mA. This expands the range of permissible input voltages, simplifying the task of circuit design. With the reduced input power dissipation, the new voltage drive photorelay is suitable for reducing the power consumption of a wide variety of equipment including probe cards, automatic semiconductor test equipment (ATE), semiconductor testers, and other similar applications. The TLP3407SR comes in a tiny S-VSON4T package with a footprint of just 2.9mm2, about 27% smaller than the existing VSONR4 package.
