4-pin SO6 package

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)
