V460LA40C

TVS or transient voltage surge suppressors, MOVs and Varistors are important components used in a variety of electronics devices. They are designed to protect electrical circuits from transient over voltage resulting from lightning or electrical noise. The V460LA40C is one such component designed to provide total protection against electrical transients. It is a high-energy surge alternative with superior pulse endurance.

The V460LA40C is a silicon-based varistor that is composed of ten sections connected in parallel. It helps protect circuits from a variety of transient surges, including those from lightning strikes and other external sources. These surges can cause catastrophic damage to the electrical devices connected to the circuit. It includes a MOS silicon controlled rectifier (SCR), which helps to dissipate large amounts of energy and prevent damage to the connected components.

To understand how the V460LA40C works, it is important to understand the concept of Varistors. A Varistor is a non-linear electrical component made up of two terminals connected to a semiconductor material (commonly metal selenide). When an electrical signal is applied to the terminals, the component will conduct until the voltage exceeds the breakdown voltage, whereupon it will quickly become an open circuit.

The Varistor coupled with the MOS SCR in the V460LA40C works together to limit the voltage applied to the circuit. When a large surge of voltage is applied, the MOS SCR draws the excess energy away from the circuit and the Varistor takes over by instantly becoming an open circuit. This prevents excessive current from entering the circuit and damaging it.

The V460LA40C is typically used in a variety of applications, including power supplies, mobile phones, industrial equipment, automobiles, consumer electronic devices and residential circuit protection. In addition to protection from lightning and other overvoltage, the V460LA40C also provides protection from short-term power surges. The varistor can operate in temperatures up to +85°C and offers a leakage current of 2mA max.

The V460LA40C is an important component for any circuit requiring protection from voltage transients and surge currents. It is designed to provide robust protection while providing superior pulse endurance. By combining the Varistor and MOS SCR components, the V460LA40C offers protection from a variety of external sources while dissipating the large amount of energy quickly and efficiently.
