TVS – Varistors, MOVs

The V39ZA05PX1347 is a TVS – Varistor, MOV (Metal Oxide Varistor) which provides an anti-surge protector to your electronic system. It is commonly used in markets such as industrial, automotive, aviation, and military. It has a broad working frequency range and is capable of providing ESD (Electrostatic Discharge) protection up to 30 KV, while providing a high surge current of 1500A at 8/20µs waveform peak.

In general, these components protect your electronic system from capacitor or inductor discharge caused by alternating current coming onto the system, or if an external power surge comes into contact with the system. The V39ZSA05PX1347 is specifically designed for AC (alternating current) applications, and it offers superior, reliable protection to systems connected to a power source.

The working principle of the V39ZA05PX1347 is relatively simple. The MOV is where the device’s core is located, and it consists of a ceramic disk of zinc oxide-based material. At the centre of the disk is a conductive contacting that is made from silver-plated copper film. When an alternating current or a surge of electrical current passes through the disk, the silver-plated copper film will react with the zinc oxide and become an electrical resistive material.

The resistive material then causes a decrease in the energy flow throughout the disk which, in turn, prevents excessive amounts of current from entering your system. Furthermore, the low-reactive nature of the resistive material also helps to protect against AC inductive and power surges. This ensures that your system remains protected despite any sort of external interference or power fluctuations.

The V39ZA05PX1347 is often used in conjunction with power supply systems, signal processors, and other electronic systems that require protective features. It is also featured in many automotive, aviation, and military systems where a need for protection against power outages or environmental interferences is present. In general, the V39ZA05PX1347 application is ideal for any type of electronic system where overload protection is required.

To summarize, the V39ZA05PX1347 is a TVS – Varistor, MOV (Metal Oxide Varistor) which provides reliable protection from AC line voltage surges. It is commonly used in industrial, automotive, aviation, and military markets, and it offers superior protection against power surges and AC inductive loads. The working principle of the device involves a decrease in energy flow when a surge of current passes through the disk, and ultimately prevents excessive current from entering your system, thus ensuring the most efficient protection possible.
