V130LU5P devices are a type of transient voltage suppressor (TVS) which also combines overvoltage protection and EMI filtering. This combination provides surge protection, overvoltage (or undervoltage) protection while attenuating unwanted EMI noise with a very low leakage current. This makes it an important component in multiple systems that require electrical circuit protection and environmental noise control.

The working principle of the V130LU5P is the suppression of transient voltage, surge and overvoltage spikes. The device is comprised of three main components -electrodes, anode and cathode. The V130LU5P is a Metal Oxide Varistor (MOV) and acts as a switch between two electrodes, turning on and off rapidly when a surge current flows. In this way, excessive current is diverted and prevented from reaching the other system components.

The MOV is composed of granules of sintered Zinc Oxide (ZnO) material which exhibits non-linear electrical characteristics; that is, its electrical resistance varies depending on the applied voltage. As the applied voltage nears its clamping voltage VP, the resistance initially increases exponentially before dropping suddenly at VP; this is known as the snap-off effect. During a surge, VP is exceeded and the MOV behaves like a low resistance path to channel the harmful current away from the protected device, while during normal operation the resistance of the MOV remains high and does not affect the normal operation of the system.

The surge protection capability of the V130LU5P when coupled with EMI filtering, makes it an ideal and cost-effective choice for applications including home appliances, lighting products, PC motherboards, power supplies, industrial motors, elevators, electric tools, automotive components and other industrial products. Its high-level surge protection capability of 130V rms and 200A peak current, as well as its wide operating temperature range of -55 to +125°C, makes it highly reliable and appropriate for different applications.

The main advantages of the V130LU5P, besides providing high-level surge protection and EMI suppressing capabilities, are its small size and low leakage current. Its low leakage current makes it especially suited for sensitive applications such as medical devices. In summary, the V130LU5P is suitable for applications where space is limited and/or EMI noise must be suppressed. It is a cost-effective protection solution allowing for high-level surge suppression with a low leakage current.
