    Circuit Protection Surge Suppressor Metal Oxide Varistor 14D561K For Frequency Converter

    What Is A Varistor?

    Varistor are voltage dependent, nonlinear devices which have an electrical behavior similar to back-to-back zener diodes. The symmetrical, sharp breakdown characteristics shown in Figure 1 enable the varistor to provide excellent transient suppression performance. When exposed to high voltage transients the varistor impedance changes many orders of magnitude from a near open circuit to a highly conductive level, thus clamping the transient voltage to a safe level.The potentially destructive energy of the incoming transient pulse is absorbed by the varistor, thereby protecting vulnerable circuit components.

    Theory of Operation

    Because of the polycrystalline nature of metal-oxide semiconductor varistors, the physical operation of the device is more complex than that of conventional semiconductors. Intensive measurement has determined many of the device’s electrical characteristics, and much effort continues to better define the varistor's operation. In this application note we will discuss some theories of operation, but from the user’s viewpoint this is not nearly as important as understanding the basic electrical properties as they relate to device construction.
