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 versions for use in harsh environment,
they fit any AC applications requiring precise control. |
