Toshiba’s New Photorelays with Low Trigger Current Contribute to Low Power Consumption in Battery-Powered Equipment

24 AUGUST 2020

Maximum trigger LED current of 1mA and increased sensitivity of the photodiode array

Toshiba Electronics Europe GmbH (“Toshiba”) has introduced two new photorelays, the TLP170AM and TLP170GM, housed in a small 4-pin SO6 package, for security systems, building automation and other industrial equipment.

The new products feature a low 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 operating life.

TLP170AM has a rated off-state output terminal voltage (Voff) of 60V. It features a typ.  on-state resistance (Ron) of 0.15Ω and constant on-state current (Ion) of 0.7A, with pulse operation of up to 2.1A. The TLP170GM is a 350V version with a typ. Ron of 28Ω, and Ion of 110mA constant current and 330mA pulse operation. Both devices have a rated operating temperature between -40°C and 85°C, to allow for a temperature margin in system-level thermal design.

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