Check out this link for On Semiconductor’s datasheet for a line of “Zero-Cross Optocoupled Triac Drivers.” The ability to zero-cross when turning on AC line voltage to some loads may be advantageous.

Diacs and triacs are often used for control of ac lines and are seeing increasing use in Internet-enabled line switches. However, the traditional approach of modeling them using bipolar transistors ...

The ubiquitous triac dimmer can still work with LED lamps, thanks to new ICs. Energy-efficient lighting is in the headlines as we approach the date at which federally mandated efficiency levels for ...
