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

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

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.

Notes:
[1] Current products TLP240GA, TLP240J
[2] Maximum turn-on and turn-off time comparison with current products above.

Applications

  • 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

[3] PIR (Passive Infrared Ray): Passive sensor, which detects humans’ access by variation of infrared radiation

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)
