Toshiba TLP170AM and TLP170GM photorelays

Toshiba Electronic Devices & Storage has launched the photorelays TLP170AM and TLP170GM in a small 4-pin SO6 package, suitable for security systems, building automation and other industrial equipment.

The products feature a maximum trigger LED current of 1 mA, which reduces input side power loss by increasing the sensitivity of the photodiode array. Using the photorelays for ON/OFF control in battery-powered security devices and various sensors should contribute to lower power consumption and longer operation of devices.

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

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