Toshiba’s New Photorelays with Low Trigger LED Current Contribute to Low Power Consumption in Battery-Powered Equipment
August 17, 2020
Toshiba Electronic Devices & Storage Corporation
TOKYO— 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 (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)
