A DIAC is a two-terminal device that can act as a switch based on the voltage applied across it. The DIACs are mostly used within the TRIAC circuits because the TRIAC does not fire a circuit symmetrically, due to the slight difference between the two halves of the device. Most of the DIACs will be having the breakdown voltage around 30 Volts, the exact breakdown voltage will be based on the type of the device. DIAC can help in switching symmetrically in both the halve cycle since it has a more even switching characteristics than the TRIAC. It is widely used in power control and switching applications.
