LA Varistor Series Should transients occur in rapid succession, the average power dissipation is the energy (watt-seconds) per pulse times the number of pulses per second. Metal Oxide Varistor – Basics Definition: The most commonly used form of a varistor is the Metal Oxide Varistor, which is also a voltage dependant and non-linear resistor connected to the electrical and electronic circuits to protect against the switch, lightning surges, and to achieve high suppression of transient voltage. Metal Oxide Varistor is a voltage-dependent resistor that is made with ceramic powders of metal oxides like Zinc oxide and some of the other metal oxides like oxides of cobalt, manganese, bismuth, etc. Basic operation, electrical characteristics, and applications will be discussed. Multi-layer varistor (MLV) devices provide electrostatic discharge protection to electronic circuits from low to medium energy transients in sensitive equipment operating at 0-120 volts dc. Susceptibility of electronic equipment to these other electric power disturbances is defined by other aspects of the system design, either inside the equipment itself or externally by means such as a UPS, a voltage regulator or a surge protector with built-in overvoltage protection (which typically consists of a voltage-sensing circuit and a relay for disconnecting the AC input when the voltage reaches a danger threshold). When it comes to application, the MOVs can be used in circuits where ever there is a risk of a surge or voltage spikes. As you can see in the diagram below, an MOV forms a connection between the hot power line and the grounding line. When subjected to a very fast, <1 ns rise-time transient, response times for the MOV are in the 40–60 ns range.

The term is only used for non-ohmic varying resistors. Varistors can fail for either of two reasons. You should choose the varistor that can dissipate more energy that is equivalent or slightly greater than the energy dissipation required during the surge that the circuit can produce. There will also be a presentation of the different MOV products Littlefuse brings to … MOVs are specified according to the voltage range that they can tolerate without damage. Although diodes do not have as much capacity to conduct large surges as MOVs, diodes are not degraded by smaller surges and can be implemented with a lower "clamping voltage". Hence MOVs are normally used in parallel with a fuse, to protect circuits from high voltage spikes. [1] Also known as a voltage-dependent resistor (VDR), it has a nonlinear, non-ohmic current–voltage characteristic that is similar to that of a diode. The Metal Oxide Varistor or MOV for short, is a voltage dependant resistor in which the resistance material is a metallic oxide, primarily zinc oxide (ZnO) pressed into a ceramic like material.

A MOV consist of approximately 90% of Zinc oxide … When the MOV is not conducting it has a high resistance up to certain voltage say 0-200Volts the Curve has a linear relationship, where the current flowing through the varistor is almost zero. Find out the amount of energy absorbed by the varistor in case of a surge. New. Both types are available over a wide range of voltages. During voltage spikes the faulted high voltage will return to normal values very soon, in those cases, the duration of the current flow will not be high enough to blow the fuse and the circuit returns to normal operation when the voltage becomes normal. Metal oxide Varistors (MOV): Since SiC Varistors had some serious drawbacks, another type of Varistors the metal oxide Varistors were developed. A simple MOV is shown in the below picture. A varistor provides no equipment protection from inrush current surges (during equipment startup), from overcurrent (created by a short circuit), or from voltage sags (brownouts); it neither senses nor affects such events.

Phys., 10, 736 (1971). The copper-oxide varistor exhibited a varying resistance in dependence on the polarity and magnitude of applied voltage. It is the amount of current drawn by the varistor when it is operating below the clamping voltage that is when there is no surge in the network. [8][9] This type of device became the preferred method for protecting circuits from power surges and other destructive electric disturbances, and became known generally as the metal-oxide varistor (MOV).
