V14MLA0805NHAUTO Circuit Protection

Transient voltage suppressors (TVS) are electrical components that protect electronic parts and circuits from overvoltage or surge events. Varistors, also known as transient voltage suppression (TVS) diodes, voltage-variable breakdown diodes, and surge suppressors, are one of the commonly used types of TVS. Metal oxide varistors (MOVs) are the most common varistors used in circuit protection. One such MOV is the V14MLA0805NHAUTO, which is used to suppress transient spikes that could potentially otherwise damage an electronic circuit.

Application Field

The V14MLA0805NHAUTO is a 14mm radial leaded varistor, with an operating voltage of 180Vrms, and a peak surge current of 4.2A. It provides a high level of protection for low power applications, and is typically used in telecommunications, consumer products, and data networks. Additionally, it can also be used in other applications such as automotive, medical, and industrial equipment.

Working Principle

The V14MLA0805NHAUTO works by limiting the voltage across its terminals during a transient or surge event. When the voltage across the MOV is below its threshold value, it behaves like a low resistance, allowing a relatively high current to flow. However, when the voltage across the MOV exceeds its threshold value, it begins to behave like a non-linear resistance, limiting the current to a much lower level than would have been allowed under normal operating conditions.

This non-linear behavior is what makes MOVs so effective at suppressing transient spikes. By providing a limited resistance to the flow of current, the MOV reduces the peak voltage to a more manageable level. This reduces the risk of damage to sensitive components in the electronic circuit.

The V14MLA0805NHAUTO is a low-power MOV, designed to protect low-power circuits from transient and surge events. Its small size makes it well-suited for applications with limited space, and it can also be used to improve the reliability of a system by providing protection from destructive power surges.

Advantages

The V14MLA0805NHAUTO has several advantages that make it popular in many different applications. For instance, it features a small size and is well-suited for cramped environments where space is at a premium. Additionally, it features a low clamping voltage and high surge capability, which makes it ideal for protecting sensitive components.

The MOV also offers excellent EMC performance. It has a low leakage current, even at high line attenuation, so it provides excellent protection against any unwanted noise or interference that could be caused by high voltage surges.

The V14MLA0805NHAUTO also offers excellent thermal stability and is designed to last for many years, even in harsher environments. It can withstand temperatures up to 105°C, which makes it ideal for many different types of applications. Additionally, it features an easy-to-use design, making installation and maintenance a breeze.

Conclusion

The V14MLA0805NHAUTO is a varistor MOV designed to protect low-power circuits from transient or surge events. It offers excellent EMC performance and thermal stability, making it ideal for a wide variety of applications. Additionally, it features an easy-to-use design, making installation and maintenance a breeze.
