The V5.5MLA1206NA is a surface mounted, unidirectional, thermally protected multilayer varistor (MLV). It is part of the TVS - Varistors, MOVs family. It is designed to provide transient voltage suppression against overvoltage transients and electrical fast transients.

The MLV is composed of multiple layer ceramic discs separated by ZnO varistor layers. It can suppress different voltage levels with different working temperatures and can protect sensitive electronic components from voltage transients. The MLV also has a wide voltage operating range, providing superior transient suppression even in low voltage conditions.

The V5.5MLA1206NA\'s field of application lies in protecting electronics from surges caused by electro-magnetic compatibility (EMC) and electro-static discharge (ESD) events. It can also protect from lightning surges, spikes, and radio frequency interference (RFI). The MLV can be used in automotive, industrial, and consumer applications such as electronic control systems, computers, cameras, mobile phones, digital equipment, and motor control systems.

The working principle of the V5.5MLA1206NA is based on the blocking and diverting of excess energy generated by voltage transients. When harmless voltage levels exist, electrons pass through the MLV by moving from the anode to the cathode. As the voltage exceeds the levels that the device can withstand, electrons are diverted away from the anode and into a breakdown region. It is this breakdown region that dissipates energy by creating a voltage drop and holding the voltage away from the protected component. With the completion of the current flow, the device reset and the protection is restored.

The V5.5MLA1206NA can provide effective protection against damaging electrical transients in many different applications. It has a high surge handling capacity and can be used with a wide range of voltage levels. It can also withstand extreme temperatures and is certified by ISO/IEC 60950-1 and IATF 16949 standards. It has an environmentally friendly design and can operate in many harsh temperatures. The thermal shut-off mechanism provides additional safety for applications needing additional protection against unexpected power transients.
