Toshiba Releases Photorelays Featuring Low Input Power and High Operating Temperature Suitable For Smart Meters

January 18, 2022

Toshiba Electronic Devices & Storage Corporation

KAWASAKI, Japan—Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched two photorelays, “TLP223GA” and “TLP223J,” with an OFF-state output terminal voltage rating of 400V and 600V, respectively. They both feature low input power, improved switching characteristics, and are housed in a DIP4 package. Shipments start today.

The new products come with a high luminous efficiency LED developed by Toshiba and have a maximum trigger LED current of 2mA. This is about 33% lower than current products[1] and allows low input power.
Faster operation is secured by lower switching characteristics (turn-on time, turn-off time): 50%[2] for TLP223GA and 75%[2] for TLP223J.

Their maximum operating temperature ratings have been extended from 85°C to 110°C, suiting them for use in equipment installed outdoors, such as smart meters. A maximum isolation voltage of 5000Vrms allows use in equipment requiring high isolation performance.

  • Smart meters
  • Security systems (PIR[3] etc.)
  • Industrial equipment (programmable logic controllers, I/O interface, various sensor control, etc.)
  • Building automation systems
  • Replacement of mechanical relays
  • 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)
