Circuit Protection Kits - TVS Diodes are a type of semiconductor device designed to provide breakdown protection to circuits. They are specifically designed to protect vulnerable components such as diodes, resistors and transistors from the damaging effects of Electrostatic Discharge (ESD) and transient overvoltage spikes.

A TVS Diode is a form of Transient Voltage Suppression (TVS) Diode which uses a specialised breakdown voltage for its working principle. The TVS Diode is primarily designed to absorb the energy from transients, while also providing over-voltage protection.

The most common application field of TVS Diodes is in the protection of circuit components that are vulnerable to ESD damage. The TVS Diode can protect the vulnerable components from any transient surge in voltage by limiting the amount of energy which is allowed into the component or circuit, thereby preventing damage.

In addition to protection from ESD and transient overvoltage spikes, TVS Diodes can also be used in pulse power and switching applications, such as in automotive applications. In such instances, the TVS diode helps reduce the risk of circuit damage that may occur due to ringing, oscillation, or parasitic inductance.

The working principle of a TVS Diode is simple. The protective diode is placed in parallel with the protected component. As a surge of energy is applied, the diode begins to conduct and absorbs the energy of the transient, preventing it from damaging the component.

When choosing a suitable TVS Diode for a particular application, the following factors should be taken into consideration: the surge current rating of the diode, the peak pulse power the diode can withstand, and the temperature range within which the diode will provide protection. In addition, the leakage current of the diode should be taken into consideration, as this represents the amount of current that passes through the diode when it is not conducting.

TVS Diodes are an essential part of any circuit protection kit, as they provide the protection needed for vulnerable components and circuits. They are widely used in a wide range of applications and provide an essential form of protection for circuit components and electrical circuits.
