KAWASAKI, Japan, January 18, 2022--(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.

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 and allows low input power.
Faster operation is secured by lower switching characteristics (turn-on time, turn-off time): 50% for TLP223GA and 75% 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.
 Current products: TLP240GA, TLP240J
