Thyristors - TRIACs

A TRIAC, or "triode for alternating current," is a three-terminal electronic component used to control the flow of alternating current. They are related to thyristors and are members of the SCR family of devices. TRIACs allow power flow in both directions and can be used to control a motor, load, or dim a light source, providing greater flexibility than an SCR.

Features and Functions of TRIACs

The TRIAC’s three terminals, labeled MT1, MT2, and Gate, serve different functions depending on the electrical characteristics required for the particular application. MT1 and MT2 are used to control current flow in either direction, while the Gate is used to trigger the device into conduction. This control is performed by applying a signal to the Gate terminal of the TRIAC. The threshold for conduction can be changed by applying a voltage to the Gate terminal. By applying the correct signal, the TRIAC is able to switch from nonconductive to conducting without requiring significant energy. This makes TRIACs more energy-efficient than SCRs and more cost-effective.
