TVS (transient voltage suppressor) - Varistors, MOVs are electrical components that safely absorb and release large transient voltages. V300LS2PX1347 is a series of high surge current varistors (MOVs), which acts as an efficient suppressing device when exposed to over-voltages conditions. In this article, the application and working principle of V300LS2PX1347 are discussed.

The V300LS2PX1347 series of high surge current varistors are specifically designed for applications such as high voltage spike protection, transients, over-voltage and inductive load protection. They are typically used as protection devices in power supplies, DC-DC converters, LCD/LED displays, medical equipment, communications equipment, IT equipment, automotive applications and other electronic systems. They are also applicable for AC line protection, surge protection, over-voltage protection, crowbar protection, and noise reduction. This MOVs has the advantages of high surge current resistance, low capacitance, fast response time and flat characteristics.

The V300LS2PX1347 is composed of a metal oxide varistor (MOV) and a ceramic capacitor. The MOV consists of a sintered zinc oxide semiconductor material with two electrodes connected to its ends. The ceramic capacitor helps to ensure stable operation of the device by providing a low impedance connection and reducing the electrical noise. The two components are connected in series and the MOV acts as a voltage-dependent resistor, dissipating the transient energy and limiting the over-voltage levels.

The working principle of the V300LS2PX1347 is based on the varistor effect. When the voltage exceeds a certain threshold, or the strength of the applied voltage increases, the varistor effect produces a resisting force that absorbs the excess energy. As a result, the reaction of the MOV reduces the over-voltage and increases the power leakage. This ensures that the system remains safe from over-voltage damage.

The V300LS2PX1347 is also designed to be very efficient at filtering out high energy transients and noise. It is capable of handling very large surge currents up to 1,000A, and it has a fast response time of 1us. The MOV also has a low capacitance and a flat current-voltage characteristic. This helps to ensure that the transient voltages are absorbed quickly and effectively.

In conclusion, the V300LS2PX1347 series of high current varistors (MOVs) are ideal for applications demanding high surge current, fast response time, low capacitance and flat characteristics. It is widely used in numerous electronic systems, such as power supplies, communication equipment and automotive systems. Additionally, its unique working principle enables it to protect the system from over-voltage and transient damage.
