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

2022-01-18 | 返回

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)
