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

2020-08-17 | Return

TOKYO— Toshiba Electronic Devices & Storage Corporation 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 (ION) of 0.7A, with pulse operation of up to 2.1A. The TLP170GM is a 350V version with an ION 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.

Applications
Security systems
Passive sensor (PIR[1]), etc.
Industrial equipment
Programmable logic controllers, I/O interfaces, various sensor controls, etc.
Building automation systems
Replacement of mechanical relays

Features
Low trigger LED current: IFT=1mA (max)
Small package: 4-pin SO6
High isolation voltage: BVs=3750Vrms (min)
