TVS - Diodes

TVS - Diodes are an important type of semiconductor components that are widely used in various industrial applications. The term stands for transient voltage surge suppressor, and they are used to protect electrical circuits from high-voltage surges and spikes. A TVS diode (also known as Transient Voltage Suppression diode) is a device that is used to suppress voltage transients (spikes) above a certain rated value, and typically below 510 volts, to protect sensitive electronics from overvoltage transients.TVS diodes are typically categorized according to whether they are unidirectional or bidirectional. Unidirectional TVS diodes are used to protect circuits from overvoltage transients in one direction only, while bidirectional TVS diodes protect from both positive and negative transients.

824521650 Application Field and Working Principle

TVS - Diodes are used in various applications across many fields, including automotive, industrial, medical, and consumer electronics. Some of the most common applications are in automotive and trucks, computers and peripherals, household appliances, and consumer electronics. In most applications, the diode is used to protect circuits from overvoltage transients, but it can also be used for electromagnetic interference (EMI) suppression in some applications.The working principle of a TVS diode is quite simple. The diode is placed between a power supply and a load. When a voltage surge occurs, the diode will block it and allow the briefrush of current through it instead, while its electric field absorbs the voltage surge. This type of diode is designed to become more conductive as the voltage rises, allowing for the increased conduction of electric current in a manner that will not damage the component or circuit.

TVS - Diodes are very important components when it comes to protecting circuits from voltage transients and electromagnetic interference. They provide a cost-effective and reliable way to protect the circuitry, while providing a relatively low resistance to the flow of current, meaning that they will not degrade the performance of the circuit that they are protecting. This makes them an integral part of many electronic designs.
