TVS (Transient Voltage Suppressors) and MOVs (Metal Oxide Varistors) are devices that are designed to protect sensitive electronic circuits from overvoltage, or the ingress of outside electrical interference or noise. These devices can be used in conjunction with other devices such as inductors, capacitors, and other components that limit the passage of high voltage transients. The B72207S0111K101 is a common type of TVS, classified as an ultra-high voltage Varistor.

Application Field

Varistors and MOVs are used in a variety of applications, from telecommunications and industrial automation, to consumer electronics. In telecommunications, these devices are used to protect signal transmission lines and telecom equipment from sudden surges or spikes in voltage. Industrial automation systems benefit from these devices as well, protecting motors, circuits, and other components from power fluctuations, noise, and outside interference. Consumer electronics such as televisions, radios, computers, and tablets rely on TVS and MOVs for protection from damage from lightning strikes and power outages.

Working Principle

Varistors and MOVs use the same basic principles to protect against high voltage transients and interference. When an overvoltage transient hits the device, it will start to clamp the voltage level to a safe operating level. This is accomplished by using two materials- a metal oxide layer, and a semiconductor material. The metal oxide acts as a resistive element, while the semiconductor provides the necessary breakdown voltage for the device to operate. The B72207S0111K101 is an ultra-high voltage Varistor with a fast response time, and it has a breakdown voltage of 7200V.

Once the overvoltage is clamped, the device will hold the voltage level steady until the transient dissipates. Varistors and MOVs use a resistance-capacitance (RC) circuit, which works by limiting the voltage rise time. The RC circuit reduces the speed at which the voltage can rise, allowing it to dissipate the overvoltage without causing any damage.

Varistors and MOVs offer many advantages over traditional surge protection devices, including better performance, faster response time, and higher levels of protection. The B72207S0111K101 in particular is an excellent choice for applications that require ultra-high voltage protection, and with its fast response time, it can help to protect sensitive electronics from overvoltage transients.
