Toshiba's TLP223GA and TLP223J Photorelays

Toshiba Electronic Devices & Storage Corporation has launched two photorelays “TLP223GA” and “TLP223J,” with an OFF-state output terminal voltage rating of 400V and 600V that feature low input power, improved switching characteristics, and are housed in a DIP4 package. These new products come with high luminous efficiency LED and have a maximum trigger LED current of 2mA.

These new photorelays feature maximum operating temperature ratings from 85°C to 110°C, suiting them for use in equipment installed outdoors, such as smart meters. Moreover, they provide an isolation voltage of 5000 Vrms which makes them suitable for applications that require reinforced insulation. 

Key Features

  • Low input power: IFT=2mA (max), VF=1.5V (max)
  • High-speed operation:
    tON=1ms (max) (TLP223GA)
    tON=0.5ms (max) (TLP223J)
  • High operating temperature rating: Topr (max)=110°C
  • High isolation voltage: BVS=5000Vrms (min)

These new devices are suitable for applications like smart meter, security systems, industrial equipment (programmable logic controllers, I/O interface, various sensor control, etc.), building automation systems, replacement of mechanical relays.
