Thyristors

Thyristors are commonly used in automation and control applications due to their simplicity and excellent power-handling capability. SIDACs and DIACs are two-terminal electronic devices conducting current in both directions. They are turned on when the voltage across their terminals reaches the breakover voltage. Thyristor power controllers like SCRs and TRIACS are three-terminal devices that are turned on via the gate terminal. Typically used to switch AC loads, TRIACs conduct current in both directions. SCRs act as rectifier diodes, conducting current in a single direction. Our thyristor selection is just a portion of the discrete semiconductors you can find using Octopart.
