Toshiba Electronic Devices & Storage Corporation has launched two new 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.

The new products come with a highly luminous efficiency LED developed and have a maximum trigger LED current of 2mA. This is about 33 percent lower than current products and allows low input power.

Faster operation is secured by lower switching characteristics (turn-on time, turn-off time): 50 percent for TLP223GA and 75 percent for TLP223J.

Their maximum operating temperature ratings have been extended from 85° 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.

Applications

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

Features

• Low input power: I_FT=2mA (max), V_F=1.5V (max)
• High-speed operation:
  t_ON=1ms (max) (TLP223GA)
  t_ON=0.5ms (max) (TLP223J)
• High operating temperature rating: T_opr (max)=110°C
• High isolation voltage: BV_S=5000Vrms (min)
