Thyristors - TRIACs: Z0107NA,412 Application Field and Working PrincipleThyristors are components in the field of power electronics that are used to control and modify electrical signals. They are widely used in the control of circuits in motors, lighting control, rectifiers, welding circuits and power control systems. One particular type of thyristor is the TRIAC (Triode for Alternating Current), a bi-directional, unidirectional voltage-controlled switch. This device, the Z0107NA,412 is a 4A 400V TRIAC, commonly used in many areas where quick turn-on and turn-off operations are required.The Z0107NA,412 has four pins labelled MT1, MT2, G and A. The ‘MT’ pins are the main terminals of the device and the most heavily used ones. They are connected directly to the main input or output lines of the power circuit, and the medium flowing through it is substantially the AC current. The ‘G’ terminal is the gate terminal, where the control signal that triggers the device is applied. Finally the ‘A’ terminal is the Anode and it is connected to the main positive power supply of the circuit. The basic operation of the Z0107NA, 412 is that when a gate current passes through the G terminal, it begins to conduct across both main terminals, and in turn provides an output signal across MT1 and MT2. This gate current can be either positive or negative, depending on the necessity of usage. When the gate current reaches zero, the TRIAC switch begins to turn off. If the gate current is left at zero for a predetermined amount of time, the TRIAC switch will fully deactivate. This time is known as the latching or holding current, and can be adjusted by using an external circuit called a snubber. A snubber is a current limiting device placed across MT1 and MT2, to slow down the switching speed of the TRIAC and reduce the amount of current surge that can be generated. In terms of practical application, the Z0107NA,412 is used in any situation where it is necessary to use a small, quick switching device. Examples of this include motors, displays, strobe lights and power tools. In these situations, the Z0107NA,412 is able to quickly switch the power on and off in order to regulate the timing of the device’s operation.The Z0107NA,412 is also used in dimmers for lighting control, a task that could not be handled by regular switches. By altering the parameters of the TRIAC, it can be controlled to provide only limited voltage and current to the lamp, thereby reducing its brightness.Finally, the Z0107NA,412 can also be used for security systems and other applications that require very precise timing regulation. It has been a popular choice for many designers in these fields, as it can provide much more precise control over the power supply than regular switches.In conclusion, the Z0107NA,412 is a versatile, reliable and efficient power control device. Thanks to its ability to quickly switch on and off in a reliably, it is a popular choice for many different tasks and applications, particularly those that require precision timing or power control.
