For many circuits in electronic products, transient overvoltage is a formidable potential issue. To protect such circuits, it is necessary to have an appropriate response time and a high level of lightning protection. By installing TVS - Varistors, MOVs, you can ensure the above protection and save the circuits from destruction due to potential surges. The VK104MK151R011P050 is a widely used component in this area. This article will explain about this specific component in relation to its application field and working principle.

What is VK104MK151R011P050

VK104MK151R011P050 is a type of Varistor manufactured by Vishay. Varistor is a non-linear voltage-dependent resistor, which behave in a very similar manner to a relay. It has a voltage-dependent resistance which provides a high level of lightning protection to the circuits. This type of Varistor is a 4-pin SMD part, with a size of 15.7mm x 11.7mm. It has a working voltage of 108V, a maximum pulse overvoltage of 155V, and a maximum surgency of 1.2kA.

Application Field of VK104MK151R011P050

This type of Varistor is suitable for a variety of systems and circuits that require basic protection against transients. Some common applications of this component include network equipment, LED lighting, consumer electronics, and telecoms systems. It may also be used to protect AC/DC circuits and automotive applications. These Varistors may also be used for signal switching applications where increased bandwidth and low noise are desired.

Working Principle of VK104MK151R011P050

This type of Varistor is basically based on a metal oxide composition with a low resistance at low voltages and a very high resistance at higher voltages. Its working principle is based on the concept of a diode, which is actually an electronic component that has a non-linear (i.e., voltage dependent) relationship between voltage and current. At a certain point, the Varistor’s resistance becomes so high that the current flow is effectively blocked, thus providing the desired protection.

When an overvoltage rate is applied to the Varistor, electrons become free from the valence band of the metal oxide composition. The number of electrons depends on the magnitude of the applied overvoltage. When the overvoltage is removed, the excess electrons return to the valence band, thus restoring the Varistor’s nominal resistance. Thus, this component has a diode-like working principle.

Conclusion

The VK104MK151R011P050 Varistor is a widely used component for providing basic protection against transients. It may be used for a variety of applications, and its working principle is based on a diode-like concept. Its small size makes it a very economical choice for many applications, and its high level of lightning protection makes it an ideal choice for circuits that are particularly vulnerable to transient overvoltages.
