TVS Transient suppression diodes: The guardian to protect electronic devices

2023-07-22

With the continuous progress of science and technology, electronic devices are playing an increasingly important role in our daily life and industrial production. However, electronic devices often face transient voltage shocks from the external environment, such as lightning strikes, electrostatic discharge and power supply voltage mutations. These transient voltage shocks can lead to equipment failure, data loss or damage, so it is particularly important to protect electronic devices from these transient shocks. In this regard, TVS transient suppression diodes play a key role. Today, Li Yang Semiconductor will explain the principle of TVS transient suppression diode and the application of TVS transient suppression diode in different industries.


I. Principle of TVS transient suppression diode:


TVS works by taking advantage of its special structural and material properties. TVS usually consists of a PN junction and a Zener diode. When there is an overvoltage or current in the circuit, the PN junction is broken down, allowing the current to flow through the Zener diode to the ground wire or other safe location. The special construction and material properties of Zener diodes allow them to maintain a stable reverse voltage at specific voltages, thus protecting other components in the circuit.


Second, TVS transient suppression diode in different industries:


TVS transient suppression diodes are used in a wide variety of electronic devices and systems, including but not limited to the following areas:


1, communications industry: In communications equipment, TVS diodes are used to protect electrical signal lines and data transmission lines to prevent overvoltage caused by lightning strikes and other damage to the equipment.


2, automotive electronics: In automotive electronics systems, TVS diodes are used to protect automotive circuits from failures of on-board electronic equipment and the impact of external voltage shocks.


3, industrial automation: In industrial automation control systems, TVS diodes are used to protect PLC, sensors and actuators and other equipment to prevent transient voltage damage caused by power supply mutations or electromagnetic interference.


4, household appliances: In household appliances, TVS diodes are used to protect televisions, computers, refrigerators and other equipment to prevent equipment failures caused by power grid voltage fluctuations or lightning strikes.


TVS transient suppression diode has the advantages of fast response, good protection effect and high reliability. It is widely used in electronic equipment, such as computers, communication equipment, automotive electronics, industrial control and other fields. In the design of electronic equipment, TVS is an important protection element, which can effectively protect electronic equipment from the impact of burst voltage or current, and improve the reliability and stability of the equipment.
