TOSHIBA RELEASES PHOTORELAYS FEATURING LOW INPUT POWER AND HIGH OPERATING TEMPERATURE SUITABLE FOR SMART METERS
KAWASAKI, Japan, Jan 19 (Bernama-BUSINESS WIRE) -- 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. This press release features multimedia.

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)
