Working Principle of VA2220K122R017

VA2220K122R017 is a type of silicon semiconductor device that acts as an electronic switch when exposed to high voltages. When a high voltage is applied, the device will conduct the current and then reduce it to a safe level. This ensures that the circuit is not harmed or damaged by any overvoltage.

The working of VA2220K122R017 is based on the principle of Metal Oxide Varistor (MOV). A Varistor is composed of two plates that are connected together by metal oxide. When a high voltage is applied, the internal resistance of the device increases and the current flow is restricted.

Since the Varistor is composed of two plates, it is called a bi-directional device. This means that VA2220K122R017 can effectively protect the circuit against both positive and negative overvoltage. Additionally, the device features low capacitance which ensures the EMC (electromagnetic compatibility) level of the device is high.

Conclusion

VA2220K122R017 Varistor has become a popular solution for protecting sensitive electronic components from excessive overvoltage. It is suitable for a wide range of high-voltage applications like communications networks, AC motors, power supplies, etc. The device works on the principle of Metal Oxide Varistor and is bi-directional. Additionally, it provides low capacitance which ensures high EMC performance.
