Toshiba America Electronic Components (TAEC) has added two mid-voltage amp-class photorelays: the 100V 3A TLP3823 and 200V 1.5A TLP3825.
“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.
There are two source-to-source connected mosfets in each relay, which can be connected in series for ac and switching, or parallel for dc switching at lower resistance,
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
Pulse measurements are t=100ms, duty=1/10
Resisistance measured in anti-series – ac operating connection
