Questions with Thyristors - DIACs, SIDACs

  • Ask: What is the function of DIAC?

    Answer: The DIAC is an electronics component that is widely used to assist even triggering of a TRIAC when used in AC switches and as a result they are often found in light dimmers such as those used in domestic lighting. These electronic components are also widely used in starter circuits for fluorescent lamps.

  • Ask: Is DIAC a thyristor?

    Answer: The term DIAC stands for the DIode for Alternating Current (DIAC), it is a bidirectional semiconductor switch that can be turned ON in both forward and reverse direction. The device is a member of the Thyristor family and it is mostly used in triggering TRIAC and other Thyristor based circuits.

  • Ask: What is breakover voltage of DIAC?

    Answer: Most DIACs have a three-layer structure with breakover voltage of approximately 30 V. Their behavior is similar to that of a neon lamp, but it can be more precisely controlled and takes place at a lower voltage.

  • Ask: What is a Sidac?

    Answer: A sidac, also called a silicon bilateral voltage triggered switch, has far greater power-handling capabilities than standard diacs. See my page on diacs. Upon application of a voltage exceeding the sidac breakover voltage point, the sidac switches on through a negative resistance region to a low on-state voltage.
