Photo relays handle up to 3A


Toshiba DIP8 photo relay

“The new products can be used to replace mechanical relays in applications including industrial equipment, general purpose inverters, HVAC, thermostats, building automation equipment and semiconductor testers,” said the firm.

They come in 8pin DIP packages, and are available with both surface-mount gull-wing and wider creepage options.

Inside, Toshiba has used its latest trench mosfet process (8th generation UMOS) to get over 1A.

Guaranteed pulsed on-state current that is three times larger than continuous on-state current, and there are no physical contacts to wear and tear
