Varistors, MOVs and TVSs, which are all forms of Transient Voltage Suppressors (TVSs), are an important component in the protection of electronic devices from voltage spikes, surges, electrostatic discharges, and other short-term voltage threats. One of the most popular brands of TVSs is V480LA80CPX2855, which is designed to provide excellent protection across a variety of commercial, industrial and military applications. This article will give an overview of the application field and working principle of the V480LA80CPX2855.

Application Field

The V480LA80CPX2855 provides comprehensive protection from transient voltage threats over long periods of time, making it ideal for a wide variety of applications. It is highly reliable and well-suited to the demanding conditions of commercial, industrial, and military applications that are sensitive to voltage spikes, surges and electrostatic discharges. It is specifically designed to absorb transient voltage events up to 80V peak in systems up to 28V DC, and can also be used in applications with AC input of up to 48V.

The V480LA80CPX2855 is especially well-suited for military and commercial aviation applications, where its high reliability and ability to absorb high-current transients make it invaluable. It can also be used in consumer electronics, such as TVs, set-top boxes, Bluetooth speakers, and gaming consoles. The V480LA80CPX2855 can handle both direct and alternating current, making it an excellent choice for power systems as well.

Working Principle

The V480LA80CPX2855 works by utilizing a metal-oxide varistor, also known as a MOV. This component is comprised of sintered granules of zinc oxide and other metal oxides, and has a non-linear, voltage-dependent resistance. When the MOV is subjected to a voltage spike, its resistance begins to decrease significantly, allowing the excess current to be diverted away from the device.

The V480LA80CPX2855 also contains a gas discharge tube, which is filled with a mixture of noble gases such as nitrogen and argon. This tube absorbs the energy of any voltage spikes or surges above the MOV\'s breakdown voltage, dissipating it as heat, and preventing it from ever reaching the device. The V480LA80CPX2855 also features a diode element, which will block any reverse voltage and protect the device from further damage.

The V480LA80CPX2855 is also designed with a clamping voltage of 18V, meaning that any voltage above this will be detected by the MOV and diverted away from the device. This voltage can also be adjusted to meet the needs of a particular application, as the protection characteristics of the V480LA80CPX2855 can be finely tuned depending on the needs of the device being protected.

Conclusion

The V480LA80CPX2855 is an excellent choice for the protection of electronic devices from voltage spikes, surges, electrostatic discharges, and other short-term voltage threats. Its metal-oxide varistor, gas discharge tube, and diode element work together to absorb and dissipate any excess voltage before it can reach the device, making it reliable and durable even in the toughest applications. With its adjustable clamping voltage, it can be tailored to meet the specific requirements of any application, ensuring comprehensive protection for any device.
