What is a DIAC? Operation Applications Circuits

The DIAC is an electronics component that is widely used to assist even triggering of a TRIAC when used in AC switches and as a result they are often found in light dimmers such as those used in domestic lighting. These electronic components are also widely used in starter circuits for fluorescent lamps. Although the term is not often seen, DIACs may also be called symmetrical trigger diodes - a term resulting from the symmetry of their characteristic curve. DIACs come in a variety of formats. As discrete components they may be contained in small leaded packages, they can be obtained in surface mount packages, in large packages that bolt to a chassis, or a variety of other packages.

This page will discuss basic triacs and SCRs. A triac is a bidirectional, three-terminal dual, back-to-back Thyristor SCR switch. This device can switch the current in either direction by applying a small current of either polarity between the gate and main terminal two. The triac is fabricated by integrating two thyristors in an inverse parallel connection.

There are several applications where it is preferred to regulate the power fed to a load. For instance: using electrical methods controlling the speed of a motor or fan. But, these methods do not allow fine control over the flow of power in a system additionally; there is an extensive wastage of power. In the present day, such devices have been developed which can allow fine control over the flow of large blocks of power in a system. These devices perform as controlled switches and can complete the duties of controlled rectification, regulation, and inversion of power in a load.

A DIAC is a two-terminal device that can act as a switch based on the voltage applied across it. In this article, we will learn more about DIAC, its construction, working and application. So let get started

Electrical & Electronic Symbols

SCRs are unidirectional one-way current devices, making them useful for controlling DC only. Because individual SCRs are more flexible to use in advanced control systems, these are more commonly seen in circuits like motor drives; TRIACs are usually seen in simple, low-power applications like household dimmer switches.

It acts exclusively as a bistable switch, conducting when the gate receives a current trigger, and continuing to conduct until the voltage across the device is reversed biased, or until the voltage is removed by some other means. There are two designs, differing in what triggers the conducting state. In a three-lead thyristor, a small current on its Gate lead controls the larger current of the Anode to Cathode path. In a two-lead thyristor, conduction begins when the potential difference between the Anode and Cathode themselves is sufficiently large breakdown voltage. Some sources define silicon-controlled rectifier SCR and thyristor as synonymous. The first thyristor devices were released commercially in
