Triode For Alternating Current (TRIAC)

A Triode for Alternating Current (TRIAC) is a semiconductor device that is used to control the flow of electrical current in AC circuits. It is a bidirectional device that can conduct current in both directions, making it useful for AC power control applications.

TRIACs consist of a bidirectional switching element that allows for the control of AC current in both directions. They are typically used in applications where AC voltage needs to be controlled, such as in lighting control, motor speed control, and power supplies.

TRIACs work by applying a small current or voltage to the gate terminal, which allows current to flow through the device. Once the current reaches a certain level, the TRIAC turns on and conducts current in both directions until the current drops below a certain threshold, at which point the TRIAC turns off.

TRIACs are commonly used in conjunction with other components such as capacitors, inductors, and diodes to form complete electronic circuits. They are often used in power control circuits that require precise control of AC voltage or current.
