TVS are surge protection components which are designed to protect sensitive electronics from transient voltage spikes. Varistors, or Voltage Dependent Resistors (VDRs), work by diverting a surge of current to ground as soon as it is detected. This is done by quickly changing the resistance of the component in response to a voltage shift in the circuit. This in turn shuts down or limits the surge current before it can cause any damage to the protected circuit.

Metal Oxide Varistors (MOVs) are a type of varistor popularly used in TVS applications. They are specific types of VDRs which utilize a nonlinear varistor material for operation - typically zinc oxide. The varistor material is sandwiched between two electrodes which are separated by a large gap. When a transient voltage is applied, the electrons in the material become mobile - creating a current sensitive to the applied voltage. This current begins to flow, leading to a reduction in the gap between the two electrodes and hence reducing resistance.

MOVs offer a precision way of dealing with voltage transients as the gap between the electrodes helps ensure that the voltage-sensitive response of the component depends primarily on the varistor material rather than on the current passing through it. This makes MOVs an ideal choice for surge protection applications. MOVs are also relatively inexpensive when compared to other VDR variants, making them even more popular.
