Transient voltage suppressors (TVSs) are an essential component in the protection of modern electronics from high energy transients. Varistors, Metal Oxide Varistors (MOVs) and silicon avalanche-diodes (SADs) are the three main types of TVSs and each has its own application field and working principles. This paper will focus on one particular product, the VE24P01750K and discuss its application field and working principle.

The VE24P01750K is a metal oxide varistor (MOV) manufactured by EPCOS. It is a radial leaded component specifically meant for transient voltage surge suppression applications and is able to provide effective overvoltage protection against lightning, switching surges, etc. The VE24P01750K is polecated with a particular feature curve; meaning its behaviour under different voltages can be described with a graph. The peak current surge capacity of the VE24P01750K is 24 kA, remote from the graph curve. There are other characteristics that are important like the resistance to over-voltage, energy absorption, insulation resistance, etc. This type of MOV is very suitable for use in electronic equipment, small office appliances, control panels and other related applications.

The working principle of the VE24P01750K is relatively simple. In the absence of an outside force, the varistor is in its “off” position. When a momentary surge voltage is applied, the varistor’s resistance drastically decreases, re-directing the current flow away from the sensitive components. This effectively diverts any potentially damaging voltages away, providing protection to the components. Once the surge is over, the MOV returns to its normally high resistance state, effectively blocking any further current flow. The MOVs non-linear features ensures that it can absorb most of the transient energy, preventing damage to electronic components.

In addition, the VE24P01750K offers some additional features that make it an appealing choice for many applications. For example, the high surge capacity and low clamping voltage provide great protection to electronic components in the event of a surge. Additionally, the small size of the component makes it easy to install in various types of equipment, and the outstanding durability and reliability of the MOV, ensures that it will perform consistently for years. As such, the VE24P01750K is a great choice for use as a transient voltage surge suppressor.

To conclude, the VE24P01750K is a Metal Oxide Varistor (MOV) manufactured by EPCOS. It is specifically designed for transient voltage surge suppression applications and provides reliable, effective protection to equipment from high energy transient spikes. Its working principle is simple; in the absence of an outside force, the MOV maintains a high resistance, blocking any further current flow. When a surge is applied, it greatly decreases its resistance, redirecting the energy flow away from the sensitive components. The VE24P01750K also offers additional features such as its small size, high surge capacity and low clamping voltage. As such, it is an excellent choice for a transient voltage surge suppressor.
