TVS - Varistors, MOVs, are electrical components that are designed to help protect electrical circuits from damage caused by sudden voltage or current spikes. The V07E140 is a type of TVS designed for use in industrial applications, such as factory automation, power distribution, and motor control. It is designed to provide protection from overvoltages and short transients.

The V07E140 is a Metal Oxide Varistor, or MOV. It is a passive, non-linear component that is typically used in parallel with the protected circuit. When exposed to a surge or transient, the MOV will conduct current and act as a clamp, limiting the voltage that reaches the protected circuit. This is done by allowing the excess current to pass harmlessly through the MOV and away from the equipment.

The V07E140 is a two-terminal MOV device constructed with zinc oxide elements and ceramic discs. The two terminals are connected to the zinc oxide elements, which are held together in a sealed construction to keep the elements inert. The two zinc oxide elements are separated by a thin thermal grease to improve the heat transfer between the elements and reduce internal resistance.

The working principle of the V07E140 is based on the non-linear characteristics of zinc oxide. When exposed to a surge or transient, the zinc oxide elements create a rectifying barrier that allows most of the current to pass through but not the voltage. This creates a voltage clamp on the circuit, limiting the voltage that reaches the protected circuit.

The V07E140 provides a maximum surge protection of 700A and a clamping voltage of 170V. It also features an operating temperature range of -40°C to +70°C and a long-term life rating of 15,000 operations. It is capable of withstanding multiple surges of higher magnitude.

The V07E140 is designed for use in factory automation, power distribution, and motor control applications. It can be used to protect sensitive electronic components from damage caused by overvoltages and short transients. The V07E140 is reliable, cost-effective, and provides outstanding performance in difficult environments.
