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.

Vishay has introduced DIP-6 and SMD-6 opto-triacs rated at 800V 100mA for home appliances and industrial equipment. Applications include controlling small loads and triggering large triacs – in ...

STMicroelectronics’ 800V 8H triacs operate at full rated current up to the maximum junction temperature of 150°C, allowing heatsinks in drives for AC loads to smaller, claims the company. The family ...

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 ...
