Low power consumption in battery-powered equipment with Toshiba's new photorelays

 TOKYO, Aug 17 (Bernama) — Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched two new photorelays “TLP170AM” and “TLP170GM” in a small 4-pin SO6 package, for security systems, building automation and other industrial equipment.
 
The new products feature a maximum trigger LED current of 1mA, which reduces input side power loss by increasing the sensitivity of the photodiode array. Using these photorelays for ON/OFF control in battery-powered security devices and various sensors contributes to lower power consumption and longer operation of devices.

TLP170AM has a rated OFF-state output terminal voltage of 60V and a constant ON-state current (I_ON) of 0.7A, with pulse operation of up to 2.1A. The TLP170GM is a 350V version with an I_ON of 110mA constant current and 330mA pulse operation.

The 4-pin SO6 package enables a minimum isolation voltage of 3750Vrms, allowing the devices to be used in equipment requiring high insulation performance.
