TVS (Transient Voltage Suppression) devices are used to protect sensitive electronics from high voltage spikes and transient over-voltage caused by electro-static discharge (ESD) and lightning. One of the most commonly used TVS devices is the Metal Oxide Varistor (MOV). V9MLA1206LH is a popular MOVs, its application field and working principle will be discussed in this article.

Application Field

V9MLA1206LH and related MOVs are widely used in industrial and consumer electronic products for surge and lightning protection. It is used in telecom infrastructure, which may include digital loop carrier (DLC) systems, wireless base stations, and switching and transmission systems. Many home and office appliances also need V9MLA1206LH-type MOVs for protection from over-voltage. In the automotive industry, these components are used for external ESD protection in engine control modules and associated air bag systems.

Working Principle

V9MLA1206LH is a non-linear resistor with a special metal-oxide construction. It features a high voltage resistance and low current resistance. When a high voltage surge occurs, the MOV will be triggered into action and will redirect the surge current away from the protected device. The MOV will essentially act as a short circuit, allowing the surge energy to dissipate as heat. As soon as the surge current reaches a safe level, the MOV automatically switches back to its high voltage resistance state and no further current flows.

The MOV has a fairly rapid response time and allows surge energy to be redirected away from the protected device in less than a microsecond. The operating voltage of the MOV is determined by its build and material used, and is usually quoted as the ”clamping voltage“. It is important to note that the MOV can still ”leak“ a small current even when the operating voltage is not exceeded.

Conclusion

V9MLA1206LH is a popular MOVs with applications in industrial and consumer products for surge and lightning protection. Its working principle is that of a non-linear resistor, with a high voltage resistance and low current resistance. The operating voltage of the MOV is determined by its build and material used, and is usually quoted as the ”clamping voltage“. The MOV can redirect the surge current away from the protected device, dissipating it safely as heat, and reset to its high voltage resistance state after the safe level is reached.
