TVS (Transient Voltage Suppressor) devices are designed to protect electronic circuitry from voltage transients induced by lightning or other sources. They efficiently work together with AC line filters, surge suppressors, and other protection techniques. Varistors (Voltage-dependent Resistor) are the most common protection devices used against voltage transients associated to electrostatic discharges. They are also called MOVs (Metal-Oxide Varistors). Both components have similar functions and characteristics, however, the means by which they provide protection are very different.

The V625LT80CPX2855 is a varistor in the 630 V product series with a nominal clamp voltage of 800 V. It has a wide range of current ratings, making it suitable for various applications within the electronics industry. This varistor is constructed by depositing MoOx (Molybdenum Oxide) on an aluminum substrate. It offers improved insulation performance in comparison to other varistors due to the applied semiconducting layer.

The V625LT80CPX2855, being a varistor, is most suitable for use in the application of over-voltage protection and surge suppression. Typically, varistors are used as transient line surge arresters, lightening surge arresters, over-voltage protection, and ground fault protection. When exposed to an over-voltage, a varistor can immediately reduce the over-voltage to a safe level. It is also capable of suppressing transients with various waveforms generated by lightning, short circuits, and other types of circuit overload.

Depending on the power rating and the clamping voltage, the V625LT80CPX2855 can be used with either AC or DC voltage. It has excellent thermal stability and withstands very high operating temperatures. It is also capable of maintaining a low residual voltage making it suitable for use in sensitive electronic circuits.

The typical working principle behind a varistor is based on the nonlinearity of its electrical-magnetism characteristics. When a voltage applied to the terminals is larger than the Varistor\'s rated value, the current carried by the device will increase rapidly. This nonlinear response can be used to absorb and divert excessive current, thus providing protection to sensitive electronic components.

In conclusion, the V625LT80CPX2855 is a reliable and high quality varistor capable of providing transient voltage and surge protection. Its unique design allows for excellent performance in a wide range of AC and DC applications. Furthermore, the nonlinear nature of varistors make them ideal for mitigating excess voltage and over-current situations.
