Photorelays handle up to 3-A drive currents

Toshiba America Electronic Components, Inc. (TAEC)* has added two mid-voltage products, the 100V TLP3823 with a 3A drive current, and the 200V TLP3825 with a 1.5A drive current, to its lineup of large current photorelays. The new products can be used to replace mechanical relays in applications including industrial equipment, general purpose inverters, HVAC, thermostats, building automation equipment, semiconductor testers, and more. The new photorelays are housed in 8-pin DIP packages, and are available with both Gull Wing (SMD) and wider creepage options.

The rate at which photorelays are being used to replace mechanical relays has accelerated in recent years. Toshiba is supporting and promoting this shift by applying its latest trench MOSFET process technology – 8th generation UMOS – to enable output currents that exceed 1A. Unlike mechanical relays, photorelays have no physical contacts subject to wear and tear, an advantage that can lead to greater product reliability. The use of photorelays also supports the development of smaller and thinner products. Toshiba’s new photorelays also offer the advantage of a guaranteed pulsed on-state current that is three times larger than that of a continuous on-state current, ensuring a bigger margin for design safety.
