Diode For Alternating Current (DIAC)

A Diode for Alternating Current (DIAC) is a two-terminal semiconductor device that is used to trigger triacs and other thyristors in AC (alternating current) circuits.

A DIAC is a type of diode that is designed to conduct current in both directions when a specific voltage is exceeded. It has a highly doped p-n junction that allows current to flow in either direction once the voltage across the diode reaches a certain threshold value. Once this voltage is exceeded, the DIAC begins to conduct and provides a low-resistance path for current flow.

DIACs are often used in electronic circuits to provide a trigger voltage for triacs and other thyristors, which are used to control the power in AC circuits. When a voltage pulse is applied to the DIAC, it triggers the triac or thyristor, allowing current to flow in the AC circuit.

DIACs are commonly used in applications such as lamp dimmers, motor speed controllers, and AC power supplies. They are often used in conjunction with other components, such as resistors and capacitors, to form complete electronic circuits.
