Introduction
The V82ZU05P is a Transient Voltage Surge Suppressor (TVS) that acts as a protector for electrical and electronic equipment from lightning strikes, surges, and other transient phenomenon. It is also known as a transient voltage surge arrester (TVSA) or a voltage surge suppressor (VSS). It is a type of protector specifically designed to protect sensitive electronic equipment from voltage spikes that can damage delicate circuitry, and to ensure the electrical and electronic equipment remain fully functional.Application Field
The application field of the V82ZU05P covers a wide range of equipment, such as computer systems, telecommunication systems, microwave ovens, medical equipment, automotive and aerospace systems, industrial automation, motor control systems, etc. due to its capability to cope with the high voltage transients that would otherwise be detrimental to the functioning of these systems and equipment. It can also be used in combination with other types of protection devices, such as lightning protection systems. The V82ZU05P is designed to absorb ESD as well as lightning-induced surges and transient over voltages, and its high surge capability makes it ideal for these applications.Working Principle
The V82ZU05P is composed of metal-oxide varistors (MOVs), which are produced with a non-linear resistance element which can provide protection from transients voltage. This device works by clamping the excess voltage between its negative and positive capacitive plates when an electrical surge passes through the device. This protects the equipment from being damaged by the high transient voltages, as the MOVs divert the surge away from its intended path while providing electrical isolation from the surge source.When the transient voltage rises, the MOVs exhibit a non-linear resistance characteristic, which allows it to absorb the transient voltage and, depending on the magnitude of the voltage, dissipates it as heat. This prevents the transient voltage from passing through the device and into the connected equipment, protecting it from damage. The V82ZU05P also includes additional protection components such as thermal fuses and current limiting resistance, which provide additional protection for the MOVs. The thermal fuse is designed to open when the temperature of the MOVs rises too high, which can protect it from thermally induced damage while the current limiting resistance helps to limit the amount of current passing through the device.Conclusion
The V82ZU05P is an ideal protection device for electrical and electronic products that require high surge protection capabilities. It is composed of MOVs which provide clamping of high transient voltages and dissipates them as heat, providing additional protection for the connected equipment. The device is also equipped with additional protection components such as thermal fuses and current limiting resistance, which enhance the protection provided.
