Product Description

DB3 Diac

When you start using it, the DIAC will be in blocking state and only very small leakage current will flow. Once the applied voltage reaches the breakdown voltage the resistance of the DIAC drops abruptly and it starts conducting which leads to a sharp decrease in voltage across it and the current starts increasing, called the Conduction State. Most of the DIACs will be having the breakdown voltage around 30 Volts. If you want to turn the DIAC off, it will remain in the conducting state until the current reaches the particular value called the holding current, where holding current is the minimum current that required for a device to keep it in the ON state and if the current fall below this level then it DIAC will stop conducting.
