TVS - Varistors, MOVs are the abbreviation of Transient Voltage Suppressor. It is a device that clamps high voltage transients. Its main functions are: clamping transient surge voltage, suppressing high voltage, disabling overvoltage, providing EMI/EMC countermeasures and so on. V320LC40B is a main product of TVS - Varistors, MOVs. It is used to limit high voltage, protect electronic equipment from overvoltage and prevent large electromagnetic radiation interference. It can be used in power supply circuits, monitors, LCD displays, computers, signal processing circuits, mobile base stations, locomotive power converters and other related fields.

V320LC40B is a resettable fuse. The maximum clamp voltage of the device can reach 320V, and the operating current is 40A. The surge current capacity can reach 1kA (8/20μs). When overvoltage occurs, this device can effectively reduce the voltage to a lower value. Then, because it is a "resettable fuse", this device can restore to its original working state after the surge voltage or surge current is gone. The response time of V320LC40B is shorter than 1ns, so the ratio of overvoltage protection can reach 100% in the test. It is often used in the field of communication protection, and is often used in high frequency applications.

The working principle of V320LC40B is rather simple. It is composed of metal oxide varistor-MOV and PTC. When the device encounters transient surge or overvoltage, metal oxide varistor-MOV can reduce the high voltage and effectively protect the circuit. At this time, the current passing through the PTC is recorded. After the overload disappears, due to PTC\'s self-heating, it restores to its cost state and the current can still pass through it. V320LC40B can provide ultra-fast response protection of pulse transient overvoltage , and its working tenacity can keep up with the rapid changes in the overvoltage environment. This device withstanding the sampling pulse voltage of 8x20μs has no breakdown, and the shape of the waveform hardly changes, which is the most prominent feature of the device.

V320LC40B is a great product of TVS - Varistors, MOVs. With this device, customers can not only excellent features of overvoltage protection, but also effectively reduce the electromagnetic interference of equipment. High quality products provide transmission efficiency and signal protection effect for the customers. With its excellent performance, it can meet the needs of different fields and occasions. It has become a popular security device for system protection and is widely used in various applications.
