TVS - Varistors, MOVs

Varistors, MOVs, and TVS are all categories of electronic components used in industrial, automotive, and consumer applications for the purpose of protecting devices from power surges.

A varistor is a type of electrical component used to protect circuits from excessive voltage. It is essentially a resistor whose resistance changes with the amount of electrical voltage applied. Varistors are available in a wide range of sizes, shapes, and voltage ratings. They are used to prevent sudden increases in voltage, resulting in a wide range of applications, from power-failure protection to surge protection for grid-tied solar power systems. Varistors can also be used in unison with other components, such as MOVs or TVSs, for applications that require more reliable and robust protection.

Metal oxide varistors (MOVs) are a type of voltage-dependent resistor that works by providing a diverting path for electrical current during a transient. MOVs have a low resistance when the applied voltage is below a certain level, and then abruptly rise to a high resistance when it exceeds that threshold. This sudden change in resistance allows them to protect electrical equipment from voltage spiking. MOVs are generally used in applications that require high surge protection, such as power distribution and telecommunications equipment.

Transient voltage suppressors (TVSs) are electrical components designed to protect circuits from transient voltages, often referred to as "spikes." In simple terms, they act as a damper to reduce the voltage that passes through a circuit. TVSs are typically used in applications that require a higher level of
