 What is a Triac component , symbol, function, structure 

Our topic today will be about explaining the most important electronic parts that are used in many projects and electronic control circuits, which is the TRIAC compound, The TRIAC is used to control electrical circuits that rely on alternating electrical current (AC current), and it can be similar to the transistor compound as it also contains three terminals and controls high-voltage electrical currents, Follow the explanation with me to learn about the triac element and how it works in electronic circuits.


Definition of the TRIAC:

The triac is an electrical element from the semiconductor family that works as a highly efficient electronic switch to control electronic circuits that operate with alternating current (AC). It is similar in terms of its working principle to the thyristor compound, except that the triac allows the electric current to pass in both directions, unlike the thyristor, which passes the electric current in one direction.  one only .

Components and terminals of the triac element
 like most electronic elements that are used in electronic control in one way or another, the Triac element has three basic terminals, which are as follows:

Triac terminals
Triac terminals 


 First pin : Gate
 Second pin : MT1
 Third pin : MT2

The working principle of triac:

 The triac element works in electrical circuits, An electric current or electrical signal, which may be negative or positive, must be introduced into the gate to allow control of the load at both ends MT1 and MT2. This is because the triac component works mainly in alternating electrical current (AC), which changes its value between positive and negative, and it can be said that the triac component is very similar to the transistor element in terms of the working principle, You can refer to a comprehensive topic about the transistor component from here.


How to test triac component :

 To check the triac component we will use a multimeter by setting it to the resistance, If we find that the resistance between MT1 and MT2 is very large during the absence of an electrical signal in the gate, this means that the electrical compound is in good condition and ready for use.


Features of triac component :

 One of the most important features of the triac element is that it allows control of electrical circuits that operate at very high electrical voltages. In addition, the triac works in electrical circuits for alternating current, which makes it an indispensable component in electrical devices that depend on alternating electrical current.  Its price is very cheap and consumes little electrical energy.


Disadvantages of triac component :

 One of the most common problems that you may encounter in using a triac compound is that the value of its operation in the positive pulse is not equal to the value of its operation in the negative pulse. To clarify further, if you operate it with 5 positive volts, you will need 10 volts to restart it with the negative pulse.


This was a comprehensive and explanatory article to explain the triac compound, which is considered the most important element of the electrical system, as well as the principle of its operation in electronic circuits. I hope you have benefited from it. Do not forget to share the topic with your friends for widespread benefit.

Why are electrical transformers measured in KVA and motors in KW

Why are electrical transformers measured in KVA and motors in KW   Why are electrical transformers measured in KVA and motors in KW Welcome to the Electron Tips website. In this topic, we will learn about the reason for measuring electrical transformers in the unit KVA (kilovolt-ampere) and electric motors in the unit of kilowatt (KW).   Why electric motors are measured in KW:  An electric motor is an electrical device that consumes effective electrical power, which is why it is expressed in units of kilowatts or horsepower because it expresses the amount of electrical energy that the motor has benefited from, and it means the actual power used for mechanical purposes and expresses the actual performance of the electric motor (effective power), because  Inefficient power will do nothing for the electric motor.   The reason for measuring electrical transformers in KVA:  Electrical transformers' primary role is to convert electrical voltages, as they do not ...

What is a perfect ground resistance value   What is a good ground resistance value Grounding is considered one of the most important systems that must be present in all electrical installations, whether in homes, buildings, or even power transmission lines. Grounding is essential for protecting people and electrical equipment from electric current leakage.  Previously, we provided a comprehensive guide on how to establish a grounding system from scratch and the key components you would need. You can view the topic [ here ]. In this article, we will explore the optimal value for good grounding resistance and how you can measure it using a Megger device. Optimal Grounding Resistance Value: Before installing a grounding system in the soil, it is essential to measure the earth resistance value using a Megger Device, especially if sensitive devices and equipment will be installed in the area. The ideal earth resistance value is zero, though achieving this value is practically impos...

Is lightning direct current or alternating current  Is lightning direct current or alternating current Many people ask about the type of electricity found in lightning, and in this small article we will explain to you whether lightning is a continuous or alternating electrical current. First, let us get to know the definition of the phenomenon of lightning and how it occurs.   Definition of lightning:  Lightning is a massive electrical discharge, meaning it contains very high electrical energy, ranging from 1 to 10 million joules. The temperature of lightning may reach 30,000 degrees Celsius, and this discharge may occur between the ground and the cloud or between two clouds together. Related articles: Can the capacitor charge the battery   The answer to the question: What is the electric current in lightning?  The electric current in lightning is an alternating electric current because it changes direction quickly and repeatedly in a short time over a short per...
