The V130LC20AP (LC20AP) is a type of varistor, which is a device used for protecting sensitive electronic components from electrical surges. Varistors are also referred to as transient voltage surge suppressors (TVS), and are one of the most important components of power systems. TVS devices are designed to conduct excessive voltage away from components or circuits – that is, to absorb the transient energy and dissipate it as heat.

The varistor works on the principle of nonlinear resistance. That is, the resistance of the device is not constant, but changes depending on the applied voltage. When the varistor is subjected to current, its resistance changes. It decreases when the current is low, and increases when the current is high. The varying resistance results in a short-circuit condition, which absorbs and dissipates the energy overvoltage.

The LC20AP is part of a series of varistors manufactured by Vishay/BC Components. The LC20AP is designed to withstand high-energy transient currents in a wide range of temperatures and voltage ranges. It is suitable for applications such as telecommunications, lightning protection, industrial control, consumer electronics and automotive applications.

This device has a dimple technology which allows for a higher current rating when compared to other varistors. Additionally, it is designed with an internal oxidation barrier to avoid fuse-like behavior and ensure long life. The device also features high peak current rating with low clamping voltages that can stand up to repeated surges.

As far as ratings go, the LC20AP has a breakdown voltage of 130 volts, with a peak current rating of 20 amperes. Its capability to dissipate surge energy is higher compared to other similar varistors with the same voltage and current ratings. The device has an International Protection designation of IP00, indicating that it is not insulated. Its standoff voltage is 1.6 volts, which indicates the protection level from high-voltage surges. The device has an insulation resistance over 1000 megaohms and an element capacitance range from 10-20pF.

In terms of operation, the LC20AP is quite versatile. It can be used in AC and DC circuits, for applications ranging from low frequency (50Hz) to high frequency (10kHz). It works in both single-phase and three-phase systems, making it suitable for many industrial and commercial applications. It can also work in a wide range of temperatures from -55C to +125C.

To conclude, the V130LC20AP is a versatile, high performing transient voltage surge suppressor, ideal for protecting sensitive electronic components from electrical surges. It has a wide range of ratings and operating parameters, making it suitable for a variety of applications. Its dimple technology and oxidation barrier ensure a long life, while its low clamping voltage and high peak current rating make it capable of handling repeated surges.
