Thyristors - DIACs, SIDACs - have a wide variety of applications in the current electronic systems, and K2200GHU is among them. In this article, we will discuss the application field and working principle of the K2200GHU, so as to give you a basic understanding of its use in modern electronic systems.

The K2200GHU is a TRIAC, which stands for Triode for Alternating Current. It is a 4-pin dual-in-line package (DIP). A TRIAC is a three-terminal device that contains two thyristors connected in inverse parallel, allowing current flow in either direction. The unique feature of TRIACs is their ability to switch on or off rapidly when triggered, making them ideal for applications requiring highly efficient and rapid switching of current. The K2200GHU is commonly used in a wide range of applications, such as phase control, lighting control, motor control, and speed control.

In terms of construction, the K2200GHU comprises of three terminals including a gate and two main terminals (MT1 and MT2). The gate is the control element, while the two main terminals (MT1 and MT2) are the power terminals. When a gate current is applied to the gate terminal, current starts to flow across MT1 and MT2, turning the TRIAC on. The direction of current flow depends on the polarity of the gate pulse. The K2200GHU has an off state current rating of 2mA, and a working current rating of up to 200mA. The K2200GHU has a working frequency of up to 200 kHz, allowing for fast switching for high frequency applications.

In terms of application fields, the K2200GHU can be used in a wide variety of different applications. One of the most common applications of the K2200GHU is as a power switching element in AC circuits. The K2200GHU is also used in AC to DC Converters, and in Variable Frequency Drives. Furthermore, the K2200GHU is also used in motor control applications, where it is used to control the speed of induction motors. Lastly, the K2200GHU is also used in lighting control applications, where it is used to dim lights and control their brightness.

The working principle of the K2200GHU is based on the use of a control element and two main terminals (MT1 and MT2). The main terminals are connected to a power source of AC, and when a current is applied to the control element (the gate terminal), it will trigger the TRIAC and cause current to flow across the main terminals in either direction, depending on the polarity of the gate pulse. The switching of the TRIAC is then triggered when the current on MT1 and MT2 reaches above a certain threshold value. At this point, the TRIAC will switch off, and then back on again when the current returns to below the threshold value.

In conclusion, the K2200GHU is a TRIAC with a wide variety of applications, ranging from phase control and lighting control, to motor control and speed control applications. It is an efficient, rapid switching device, capable of switching currents up to 200mA, with a working frequency of up to 200 kHz. The K2200GHU works based on the principle of a control element and two main terminals, and its switching of current is triggered when the current across the main terminals reaches a certain threshold value. It is a valuable component in many electronic systems, and is widely used in various industries.
