TVS (Transient Voltage Suppressors) and Varistors (or VRs) are two popular products used to protect electrical systems from overvoltage surges. They work by dissipating the extra energy of the surge as heat. This is accomplished either by shorting out the overvoltage pulse (TVS) or diverting it to earth or another device (Varistor). Sometimes, surge suppressors are being used in combination to provide additional protection.

V130LA2PX2855 is a specially designed bidirectional varistor for automotive electronics system applications. It is used in surge protection circuitries of powertrain and body electronics, driver\'s systems and other automotive applications. In addition to surge protection, it also provides EMI/RFI filter processing capability. V130LA2PX2855 operates in temperature ranges from -40℃ to 125℃.

The working principle of V130LA2PX2855 is to offer voltage limitation protection in bidirectional polarity for automotive electronics systems. It is composed of a ceramic body and two metal contacts with a ZnO layer. Its main parameter, the clamping voltage, is determined by the size of the ZnO layer, the distance between the electrodes and the thickness of the dielectric. During operation, when the voltage on the terminals exceed the peak breakdown voltage, the ZnO layer gets de-insulated and a current flows through it, leading to a spark. This spark limit the voltage to a level lower than the peak breakdown voltage. The heat generated due to this sparking dissipates the energy of the surge, thereby protecting the system.

V130LA2PX2855 varistor can be used for transient voltage suppression (TVS) and electromagnetic interference (EMI) protection in automotive electronics systems. It offers excellent low clamping voltage, high surge handling capability and high surge current ratings. In addition, it is designed to meet the transient requirements of automotive electronics applications up to 100A peak current. It is also available in a wide range of resistance values and operating temperatures, making it suitable for various applications.

V130LA2PX2855 is a versatile protection device and is suitable for a variety of automotive applications. It provides high surge handling capabilities, excellent protection against overvoltage conditions, and consistent performance across different temperature ranges. It is also designed to meet the requirements of automotive transient applications up to 100A peak current and is available in a wide variety of resistance values. This makes V130LA2PX2855 a highly reliable and cost-effective solution for surge protection in various automotive electronics systems.
