TVS - Varistors, MOVs

MLVA06V18C150-R is a surface mount device (SMD) varistor which is also known as a transient voltage suppressor (TVS). Varistors are primarily used in application fields where transient voltage spikes need to be suppressed.

They are commonly employed in defense, industrial, communication, medical, automotive and aerospace applications, among others. As MLVA06V18C150-R is designed to withstand harsh environments, it is a very reliable device and extensively used in ruggedized applications.

Varistors Working Principle

A Varistor is a voltage-dependent resistor made of metal-oxide semiconductor material. It is a non-linear device, meaning that it will react differently as the voltage across it changes. This means that a varistor can be used to protectagainst transient over-voltage and surge current. A Varistor can also be used in combination with other components such as fuses, voltage regulators orlightning arresters to provide protection against overvoltage and transients.

The working principle of MLVA06V18C150-R starts with the metal-oxide semiconductor material. This material conducts under normal operating conditions. When an electrical surge or transient protects the device, itbypasses the current through its semiconductor structure, thus avoiding any damage to the component. As the current passes through the material, the voltage across the device increases thereby providing voltage protection.

MLVA06V18C150-R also has a peakCLAMP type of varistor which senses overvoltages or transients. On sensing theovervoltage, the peakCLAMPvaristor will act to reduce the voltage to a safe level by absorbing the spike. This protects the device from any damage due to overvoltage or transients.

Applications of MLVA06V18C150-R

MLVA06V18C150-R is used in a wide range of applications which require transient protection. This includes A/V equipment, automotive, telecom, computers, displays, industrial control, power supplies and more. Due to its reliability and rugged construction, it is also used in aerospace and defense applications.

In automotive applications, MLVA06V18C150-R is used to protect against voltage spikes from the alternators which can damage sensitive circuits. It can also be used in combo with an automobile fuses and high-side switches to prevent a vehicle’s lighting system from over-drawing current.

In the telecommunications industry, these varistors are used to protect sensitive equipment from ESD events and unexpected voltage changes. They are also used to control the flow of electricity in power supplies which monitors and controls the amount of electricity going to and from a device.

Overall, varistors such as MLVA06V18C150-R provides a reliable protection of electronic components from voltage and current spikes, transients, and ESD events in industrial, defense, aerospace, and numerous other application fields.
