TVS - Varistors, MOVs: V130LA20BP application field and working principleOverview

The V130LA20BP is a highly efficient, low-voltage, bidirectional surge protection device designed to protect against overvoltage and overcurrent events up to 30A. It features two independent 1500W unidirectional protection channels and a thermally protected gas tube designed to withstand 1000W peak pulse power per line. This product is suitable for protecting against lightning, transients, inductive loads, power switching, overcurrent and/or overvoltage conditions in a variety of applications.Varistors, MOVs (Metal Oxide Varistors) are often referred to as overvoltage protection devices (OVPDs) and are commonly used to provide protection against transient overvoltages in either AC or DC circuits. They are simple, low-cost components that can be designed and manufactured in different shapes and sizes depending on the specific application requirements. A varistor is usually composed of metal oxide granules and other materials that provide a non-linear resistance vary much more with voltage than with temperature.The V130LA20BP contains two separate bidirectional 1500W channels, each in a V-shaped configuration, that are designed to withstand two different voltage sensitivities in each direction. Its n-type characteristics bypasses the current until the voltage reaches a certain threshold, then the device turns on and provides a low-impedance path to ground or a low-impedance path to an overcurrent protection device. This allows it to provide robust transient protection while minimizing power losses in the circuit.When connected in series with the load, the positive terminal of the V130LA20BP is connected to the load circuit and the negative terminal is connected to the ground. The connected branch will then act as an impedance element that will dynamically react to overvoltage transients by diverting the current away from the load, thereby providing improved protection. Furthermore, the device can also be used for single-ended or ground-referenced applications.An important factor to consider when selecting the V130LA20BP is its load current capability. The device is designed to provide up to 30A MPP (multi-pulse power) in both directions. Additionally, it is easy to install in any desired circuit configuration, for example with a clamp-type copper bar connection, soldering or welding.One of the major advantages of using the V130LA20BP for overvoltage protection is its low leakage current throughput, which suggests that the device will not create a circuit self-destructive current loop. Additionally, it features a very low internal resistance, which allows it to achieve better overvoltage protection performance.In summary, the V130LA20BP is a highly efficient, low-voltage surge protection device designed to protect against overvoltage and overcurrent events up to 30A. Its two independent 1500W unidirectional protection channels and thermal protection elements make it one of the best solutions for protecting your equipment from transients, inductive loads, power switching, and overcurrent events. The device also features a low leakage current, making it an ideal choice for almost any application.
