TVSs (Transient Voltage Suppressors), MOVs (Metal Oxide Varistors), and V26SM20 are electrical protection devices that are commonly used in various circuits and systems. TVSs are mainly used to protect integrated circuits (ICs) from transient high voltage surges, while MOVs are used to provide over-voltage protection, and V26SM20s are used mainly for line-to-line over-voltage protection.

The V26SM20 series is a popular Metal-Oxide-Varistor (MOV) developed by the electronics component manufacturer Visaton. This series of movs is designed for use in line-to-line over-voltage protection, and is commonly used in the industrial and consumer electronics market. The V26SM20 features an impressive voltage clipping ranging from 32V to 1500V (at 1mA) and can handle a current of up to 2.4A. The V26SM20 also features a low operation capacitance of 0.01pF and a maximum breakdown voltage of 45V.

The main application of the V26SM20 is for line-to-line over-voltage protection, which is typically found in audio/video systems. This protection is necessary to ensure that no excessive voltage is applied to the components of the system, which could potentially damage the circuit. The V26SM20 serves to limit the voltage to the desired level, thus preventing any overvoltage from causing damage. In addition to the protection of audio/video systems, the V26SM20 can also be used in AC/DC power supplies, personal computers, and household appliances.

The working principle of the V26SM20 is very simple. When the voltage applied to the device exceeds the specified breakdown voltage, the V26SM20 begins to conduct. As the current passing through the device increases, the resistance of the MOV decreases and it continues to conduct until the voltage is safely regulated to the desired level. This current limiting action helps to protect the circuit from over-voltage or transient voltage surges.

The V26SM20 is a very reliable and cost-effective solution for providing over-voltage protection to audio/video systems, AC/DC power supplies, personal computers, and household appliances. Its impressive voltage clipping, low operating capacitance and high surge ratings make it ideal for use in many applications. It is also very simple to install and requires minimal maintenance, making it a great choice for anyone looking for a reliable over-voltage protection solution.
