What is a DIAC ( DIode for Alternating Current )?

A DIAC (DIode for Alternating Current) is a two-terminal semiconductor device primarily used for switching alternating current (AC) signals. It begins to conduct when the voltage across it exceeds a certain threshold, and it stops conducting when the reverse voltage is applied. This allows the DIAC to act as an efficient switch for AC circuits. Typically, DIACs are used in conjunction with TRIACs and other composite devices to control power in various applications such as motor control, light dimming, and audio equipment. They offer simple and effective control of AC power.

Application of DIAC ( DIode for Alternating Current )

✅Motor Control:
DIACs are used in motor control circuits to adjust the speed of AC motors. When combined with TRIACs, they allow for smooth speed regulation.
✅Light Dimming:
Used in lighting systems, DIACs enable light dimming when paired with dimmer switches, providing energy-efficient control over brightness levels.
✅Audio Equipment:
In audio equipment, DIACs act as switching elements to regulate power and smoothly adjust volume levels.
✅Temperature Control Systems:
In temperature control systems, DIACs are used for efficient switching of heaters and cooling devices, enabling precise temperature regulation.
