Triacs

Thanks to their bidirectional structure, Triacs are useful in controlling full-wave AC applications. They can be used as an ON/OFF switch, replacing efficiently electro-mechanical relays (providing high degree of flexibility through electronic control, and superior reliability).

They are also capable to control power level through AC loads, thanks to a simple phase control circuit.
Available in general purpose standard configurations, high commutation performance series with ST Snubberless™ technology, or high-temperature Triacs for use in harsh environment, they fit any AC applications requiring precise control.
