TVS - Varistors, MOVs: V660LU100BP Application Field and Working Principle

Transient Voltage Suppressors (TVS) are a class of protection devices intended to protect sensitive circuits from the damaging effects of transient electrical disturbances such as electrostatic discharge (ESD), voltage transients and induced lightning. TVS devices are designed with two main components: varistors and metal-oxide varistors (MOVs). Varistors and MOVs work in tandem with each other to protect circuit elements from excessive voltage surges.

A varistor is an electrical component designed to provide protection against transient voltage surges. Varistors are usually constructed from ceramic or semiconductor materials and are designed to reduce an input voltage to a lower, safe level. They are also known as voltage dependent resistors (VDR).

Metal-oxide varistors (MOVs) are components composed of zinc oxide ceramic and a metal electrode, which work together to clamp down the input voltage to a safe level. MOVs are designed specifically to withstand and dissipate large amounts of current. MOVs have a high-power capacity and can also be used in very small sizes, making them a popular choice for many applications.

The V660LU100BP is one of the most popular models of varistors and MOVs used in electrical protection circuits today. The V660LU100BP is a bidirectional varistor/MOV combination designed to provide protection against both static pressure (static electricity) and transient surges. The V660LU100BP is rated at 660 volts, with a clamp voltage of 100 volts and a maximum peak surge current of 11.5 kiloamperes (kA). This makes it an ideal choice for a wide range of applications, from medical equipment and consumer electronics to industrial machinery and automotive applications.

The V660LU100BP combines the protection of both varistors and MOVs. The varistor component works by limiting the input voltage to a safe level, while the MOV component dissipates the surge current and reduces the chances of permanent damage to the circuit. The combination of these two components provides the best protection against transient surges and static electricity.

In operation, the V660LU100BP works by diverting the energy of the transient voltage surge or static discharge away from sensitive circuit components. The varistor component limits the voltage and prevents it from exceeding the rated voltage level, while the MOV component dissipates the diverted energy as heat, protecting the circuit from overheating and possible destruction.

The V660LU100BP is suitable for use in a wide variety of applications, from consumer electronics to automotive applications. It is designed to provide superior protection against transient voltage surges or static discharges, and is the ideal choice for applications that require reliable protection from electrical disturbances. Its compact size and high-power capacity make it the perfect choice for many applications.
