The principal components used to reduce or limit high voltages can include one or more of the following electronic components: Metal oxide varistor – The metal oxide varistor (MOV) contains a material, typically granular zinc oxide, that conducts current (shorts) when presented with a voltage above its rated voltage. MOVs typically limit voltages to about 3 to 4 times the normal circuit voltage by diverting surge current elsewhere. They have finite life expectancy and "degrade" when exposed to a few large transients, or many more smaller transients. They may be connected in parallel to increase current capability and life expectancy, providing they are matched sets (MOVs have a tolerance of approximately 20% on voltage ratings). "Degrading" is the normal failure mode. They usually are thermal fused or otherwise protected to avoid short circuits and other fire hazards. A circuit breaker is different from the internal thermal fuse. If a surge current was so excessively large as exceed the MOV parameters and blow the thermal fuse, then a light found on some protectors would indicate that unacceptable failure. MOVs are the most common protector component in AC power protectors.

Transient suppression diode – A type of zener diode called an avalanche diode or suppression diode will limit voltage spikes. These components provide the best limiting action of protective components, but have a lower current capability. Voltages can be limited to less than 2 times the normal operation voltage. If current impulses remain within the device ratings, life expectancy is exceptionally long. If component ratings are exceeded, the diode may fail as a short circuit. Protection may remain but normal circuit operation is terminated. Due to their relatively limited current capacity, transient suppression diodes are often restricted to circuits with smaller current spikes. Transient diodes are also used where spikes occur significantly more often than once a year. This component will not degrade with use. A unique type of transient diode (transzorb or transil) contains reversed paired avalanche diodes for bi-polar operation. Another type is paired in series with a diode to provide low capacitance as required in communication circuits. Gas discharge tube (GDT) – These rely on a gas trapped between two electrodes that is ionized by the high voltage to conduct electrical current. GDTs can conduct more current for their size than other components. Like MOVs, GDTs have a finite life expectancy, and can take a few very large transients or a greater number of smaller transients. GDTs also take time to trigger permitting a higher voltage spike to exist before the GDT conducts significant current. It is not uncommon for a GDT to let through pulses of 500V or more of 100ns in duration. In some cases additional protection is necessary to prevent damage due to this effect. GDT create a short circuit when triggered, so that if any electric power (spike, signal, or power) is present, the GDT will short this, and will continue conducting until all electric current sufficiently diminishes. Unlike other protector devices, a GDT will conduct at a voltage less than the high voltage that ionized the gas. Gas arrestors are often used in telecommunication equipment. Due to an exceptionally low capacitance, GDTs are commonly used on high frequency lines. A selenium voltage suppressor is a "clamping" semiconductor similar to a MOV, but it does not clamp as well. However, it usually it has a longer life than a MOV. It is used mostly in high-energy DC circuits, like the exciter field of an alternator. It can dissipate power continuously, and it retains its clamping characteristics throughout the surge event, if properly sized.
