TVS or Transient Voltage Suppressors are part of over-voltage protection devices utilized in electronics and electrical equipment. TVS provides transient over-voltage protection.

The V8ZA1 is a multi-layer varistor, also known as the Metal Oxide Varistor (MOV), belonging to the TVS family. MOVs protect sensitive electronic equipment from transient overvoltage conditions created by voltage spikes from the electrical power grids or long flexing power cables. These devices are widely used these days due to their large voltage absorption capacity.

The V8ZA1 varistor housing is made up of two metal-oxide layers that sandwich between two electrodes. This construction forms a leakage-free connection and provides excellent electrical properties. The metal-oxide layers are made up of high-quality semi-crystalline particles, which provide increased insulation. Additionally, the two layers of electrode materials provide low resistance around the semi-conductor in comparison to the metal-oxide layers.

This MOV offers excellent protection against transient overvoltages and is suitable for harsh environmental conditions. The V8ZA1 can operate without deterioration in temperature ranges between -40°C and+110°C and can withstand up to 2,000 V of surge energy.

The working principle of the V8ZA1 utilizes a combination of the varistor’s electrical properties, such as low DC resistance and high AC impedance. This enables the device to absorb the energy released in transient overvoltages and protects the sensitive electronic equipment from damage. When the transient voltage is encountered by the electrodes, the varistor is activated and begins to absorb the energy from the voltage spike. The energy is then dissipated, preventing the transient voltage from propagating through the electronic equipment.

The V8ZA1 varistor is designed to protect a wide range of common electronic equipment such as communications systems, power supplies, medical equipment, and automotive systems. It is suitable for use in both surface mount and through-hole applications, providing reliable performance and superior protection against transient voltage spikes.

The V8ZA1 is commonly utilized in applications that require reliable and over-voltage protection. Its reliability in a variety of harsh environmental conditions make it an ideal choice for protecting delicate electronic components. The V8ZA1 is easy to install and requires no external circuitry, making it a cost-effective solution for protecting sensitive electronic equipment.
