TVS (Transient Voltage Suppressors) devices, such as varistors, MOVs (Metal Oxide Varistors) and other components, provide a means of limiting and suppressing transient voltage on sensitive electronic circuitry during an over-voltage event. The application field and the working principle of a 2859589 TVS has multiple uses and following details can assist in understanding of how a transient voltage suppressor works.

How Does TVS - Varistors/MOVs Work?

To understand the working principle of a TVS and its associated components, varistors and MOVs, first the terminology needs to be defined. Varistors are devices designed to protect against high voltage through a movable “electrical contact”. MOVs are devices that absorb and dissipate energy from a sudden electrical current flow, which is created during an over-voltage event. They are both a type of TVS.

How does it work? Both varistors and MOVs have protection curves which show the amount of pressure the device can handle before it is destroyed. This pressure is known as clamping voltage. The higher the voltage, the higher the clamping voltage, which should be kept within reasonable limits to prevent device damage.

During an over-voltage event, the varistor or MOV will “clamp” the voltage to a safe level and protect the circuit. This prevents electricity from traveling longer distances and potentially damaging the circuit. In addition to this, the varistor or MOV will “absorb” or divert the electricity into the ground, preventing further damage.

The application of a 2859589 TVS is dependent on the application field. For example, it may be used for power lines, phone lines, computers, or any other type of device or component needing protection from over-voltage events. In some cases, it may be used in conjunction with other components, such as voltage regulators and other types of protection devices. The exact application will depend on the individual requirements of the product being protected.

When choosing a TVS device, it is important to select one that is appropriate for the environment and application. Variables to consider when selecting a TVS include operating temperature, surge rating, peak impulse current, and other voltage ratings. In addition to the specifications of a device, it is important to consider the application field and its environment. TVS is used in a wide range of applications, from consumer electronics to automotive applications, and it is important to consider the environment of the application before selecting a device.

In conclusion, the 2859589 TVS can be used in many different application fields and its working principle is fairly straightforward. It is designed to protect a circuit from an over-voltage event and clamp the voltage to a safe level. Additionally, it is important to consider the environment and specifications of the device before selecting a TVS as it can help to ensure it is suitable for the application.
