Transient Voltage Suppressors (TVS) are widely used in various electronic applications like computers, automotive, and communication equipment. These components are designed to protect other components and devices from voltage spikes that occur due to sudden changes in voltage or current. The most popular type of TVS are Varistors, Metal Oxide Varistors (MOVs) and Zener diodes.

The V130LA10CPX2855 from Vishay is a TVS metal oxide varistor (MOV) with a voltage rating of 28V. The component has a higher load current than other types of MOVs, making it the ideal choice for applications that require reliable surge protection. The V130LA10CPX2855 features a round, surface mount package and is RoHS compliant.

V130LA10CPX2855 Application Fields

The V130LA10CPX2855 is suitable for applications that require protection against transient voltage and current surges. This device can be used in industrial and commercial products such as consumer electronics, computers, laptops, automotive, telecommunications, and medical equipment. It’s also suitable for products that have to meet the standards for electromagnetic compatibility (EMC) and radio frequency interference (RFI).

The V130LA10CPX2855 is particularly useful for applications that require frequent hot-switching, because its capacitance value and maximum peak current are less than those of other types of MOVs. The component can also function as an EMC filter, since it can reduce or eliminate interference from radio frequency fields. Moreover, its lower operating temperature makes it a good choice for applications that require stable and precise circuit operation.

V130LA10CPX2855 Working Principle

The V130LA10CPX2855 is a type of MOV that works by “clamping” the voltage applied to it to a specific value. It is different from a Zener diode, which dissipates electrical current and maintains a voltage drop across its terminals. When an overvoltage occurs, the V130LA10CPX2855 quickly interrupts the circuit and suppresses the voltage. This prevents other components from being damaged by the surge.

The device has a cylindrical body surrounded by two internal metal oxide layers. The lower layer is made of zinc oxide, while the upper layer is made of aluminium oxide. When an overvoltage is applied, the zinc oxide layers become conductive and divert the extra voltage away from the load. The aluminium oxide layer prevents the device from becoming permanently damaged.

The V130LA10CPX2855 also exhibits high surge capability and excellent reliability, making it an ideal choice for various protection applications. Its smaller size also makes it easier to install, and it can sometimes be mounted directly onto a circuit board without the need for extra space or accessories.

Conclusion

The V130LA10CPX2855 metal oxide varistor is an ideal transient voltage suppressor for applications that require reliable voltage regulation and surge protection. It features a low maximum peak current, high surge capability, and excellent reliability. It can also be used as an EMC filter and is suitable for hot-switching applications. The component’s low operating temperature, small size, and easy installation make it an attractive choice for a variety of industrial and commercial applications.
