TVS - Varistors, MOVs is a type of surge protection device or SPD. It is used to protect equipment and systems from dangerous sudden surges in electrical current that might damage or ruin its function. V82ZA4PX2855 is a type of TVS - Varistors, MOVs designed and manufactured to provide maximum protection against potential power surges, along with excellent stability and high performance. This device is commonly used in a wide range of industries including telecommunications, automotive, aerospace, medical, and industrial automation.

The V82ZA4PX2855 was created by combining varistor and metal oxide varistor technology in one package. It is highly effective at preventing damages caused by overvoltage events, which can include lightning strikes, switching surges, power line disturbances, induced voltages, and external transients. This device can be used for surge and EMI protection with low thermally induced capacitance and low clamping voltage.

The V82ZA4PX2855 is an efficient and reliable surge suppression device that can handle currents up to 10,000A with a maximum clamping voltage of 10V. It is also available with an integrated thermal disconnect feature, which allows the varistor to safely shut off if the device gets too hot. The device is RoHS compliant, UL recognized, and ISO9000 certified.

The V82ZA4PX2855 is designed with a bidirectional symmetrical structure which enables uniform absorption of surges from both AC and DC sources. This symmetry helps minimize asymmetrical power deformations which are a common source of equipment failure. Additionally, the chips in the device are coated with a non-conductive material which reduces leakage currents, offering superior protection against short-circuiting and overvoltage.

The working principle of the V82ZA4PX2855 is based on a non-linear resistance characteristic. The varistor works by clamping the voltage to a predetermined level, providing an additional safety margin. As the magnitude of the voltage increases, so does the varistor’s resistance. This reduces the current flow, limiting the strong surge current. The MOV devices use a Zinc Oxide element to offer protection against overvoltage.

In addition to providing effective protection from overvoltage events, the V82ZA4PX2855 also features excellent heat dissipation and low thermal resistance. Its low profile, high power and low inductance characteristics allow it to fit into a wide variety of applications. This highly versatile device is capable of meeting almost any overvoltage protection requirement.
