TVS (Transient Voltage Suppressors) and MOVs (Metal Oxide Varistors) are electrical protection devices used to protect sensitive electronics from damaging high voltage transients. V82ZU2PX2855 is a TVS designed to protect against transient overvoltage events such as Lightning, inductive load switching, or electrostatic discharge. It is made from a special proprietary alloy that has a breakdown voltage of 28.5V.

The V82ZU2PX2855 is a monolithic device that combines a zinc oxide (ZnO) varistor element with a low-capacitance diode. The ZnO varistor element provides protection against transient overvoltages, and the reverse-biased diode protects the device against static overvoltage events and inductive kick-back. The combination of these two elements helps to protect the device from damage caused by transients, while also providing a fast response time for effective protection.

The working principle of the V82ZU2PX2855 is based on the ability of the ZnO varistor element to absorb electric energy when an overvoltage situation occurs. During an overvoltage event, the ZnO element produces a negative-going voltage drop that rapidly increases in magnitude. As the voltage drop reaches a critical level, the ZnO varistor switches from the non-conductive to conductive state, thus allowing the overvoltage energy to be rapidly diverted away from the protected circuit. The reverse-biased diode further helps to protect the device from damage by limiting the level of current allowed to flow through the element.

The V82ZU2PX2855 has a number of applications in the electronics industry where overvoltage protection is essential. It is commonly used in automotive electronics, telecom equipment, LED Lighting, electrical appliances, and medical equipment. Due to its fast response time and high surge current rating, the V82ZU2PX2855 is also suitable for a variety of AC and DC power line protection applications. The device is also popular for applications where physical size is an issue due to its compact design.

In conclusion, the V82ZU2PX2855 is an ideal device for applications that require fast and reliable overvoltage protection. It is a monolithic device that combines a ZnO varistor element and a reverse-biased diode for effective protection against transients, static overvoltage events, and inductive kick-back. The device has a wide range of applications in the electronics industry and is highly regarded for its small size, fast response time, and high surge current rating.
