VC1812K801R017

Transients suppression has become an increasingly important concern for engineers designing and operating reliability systems. Many automatic systems, especially those in harsh environments, have to regularly contend with cycling surges and electrostatic discharges (ESDs). To protect these systems, TVS-varistors, MOVs (metal oxide varistors) are employed to withstand these high-voltage disturbances. The VC1812K801R017 is a compact, wide bandgap TVS-varistor capable of accommodating both industrial and consumer applications.

A TVS-varistor is generally a single component with two electrodes, and two different materials layered across it. The two materials are designed to have different dielectric properties, allowing the TVS-varistor to separate the charges on both sides of it, thereby achieving their purpose. The TVS-varistor can also be constructed from the same material, however the more common construction is the two-material type.

The VC1812K801R017 is an example of a TVS-varistor designed for industrial and consumer applications. It features a wide range of breakdown voltages, ranging from 18V to 12KV. This makes it suitable for applications with a variety of voltage requirements. It is also designed with a low reverse leakage current in order to reduce power consumption. Additionally, it can withstand high reverse energy, making it ideal for high-energy applications such as automotive or military applications.

The working principle of the VC1812K801R017 is closely related to the TVS-varistor in general. During normal operation, the varistor is a non-conductive device whose voltage will remain at its rated level. However, when a transient voltage event occurs, the varistor will begin to conduct current, thus providing protection for the system. This protection is achieved by the breakdown of the varistor’s material layers, allowing the current to pass through it and into the ground instead of through the system.

The VC1812K801R017 is capable of suppressing both overvoltage and static discharge currents. In the case of an overvoltage, the varistor will clamp the voltage, allowing it to reach a predetermined peak. This peak is lower than the voltage of the system, thus providing it with protection. In the case of an electrostatic discharge, the varistor will dissipate the energy and reduce the voltage in the system, thus preventing it from suffering damage.

In conclusion, the VC1812K801R017 is a versatile TVS-varistor that is suitable for use in a variety of applications. It can provide excellent protection against both overvoltage and ESD events, ensuring the reliability and durability of the system. Additionally, its wide range of breakdown voltages make it ideal for a variety of voltage requirements.
