Thyristors, which are a type of semiconductor device, are commonly divided into two broad categories: DIACs and SIDACs. This article explores the application field and working principle of K2200SRP, a specific type of DIAC.

K2200SRP Application Fields

K2200SRP is primarily used for electronic triggering and energizing circuits, providing an ideal power source for digital and analog control circuits. It has a wide range of applications, including:

• Automotive electronics, where it is used for AC, DC and pulse-width-modulation (PWM) applications
• Industrial electronics, where it provides a reliable means of energizing control circuits and triggering switches
• Mobile device electronics, where it is used for energizing digital circuits
• Consumer electronics, where it is employed for controlling the energizing of small electronic devices.

K2200SRP Working Principle

K2200SRP works on the principle of bidirectional conduction and consists of two integrated thyristors junctioned together. The device is made up of two PN junctions, which are arranged in an opposing parallel manner. When an external voltage source is applied to the thyristors, electrons in the junction are attracted to the positive end, and then the process is reversed. This opposite motion of the electrons causes current to flow through the device, which triggers the thyristors.

The device\'s conduction behavior is determined by its reverse breakdown voltage. This voltage, known as the Peak Current Switching Voltage (PCSV), decides if the device is reset when the voltage applied to it falls below PCSV. Additionally, the device is also reset if the current reaches the peak current rating. The functional current of the device (I F ) is applied until a minimum current of 80 uA is reached.

K2200SRP is a symmetrical thyristor, meaning that it is triggered by increasing voltages from both its positive and negative terminals. When a triggering voltage is applied between the two terminals, a conduction path forms between them, allowing current to flow through. The device\'s triggering voltage is about 2.2V and its peak current rating is 800mA. It is capable of operating under temperatures ranging from -40C to 125C.

Conclusion

K2200SRP is a type of DIAC thyristor, commonly used for a variety of applications. The device works on the principle of bidirectional conduction, with a reverse breakdown voltage of 2.2V and a peak current rating of 800mA. The device is triggered by an increasing voltage from either its positive or negative terminals. With its broad range of applications in automotive, industrial, mobile, and consumer electronics, K2200SRP is a reliable and cost-effective power source for various digital and analog control circuits.
