TVS - Varistors, MOVs are two very important elements in the field of surge protection. TVS stands for Transient Voltage Suppressor, while MOV stands for Metal Oxide Varistor. In this article, we\'ll focus on one particular TVS - Varistors example, VC120630D650RP, and discuss its application field and working principle.

The VC120630D650RP is a 30V rated component with a low capacitance (0.02pF). It is designed to be used as a voltage clamp over its operating voltage range and is typically used for ESD protection, power management, and transient voltage protection. It is also well suited for use in automotive, medical, and military applications, as well as hazardous-location installations. In addition, it is compliant to RoHS and UL 94V-0 standards and has a low-impedance packing.

To understand the working principle of the VC120630D650RP, it is helpful to understand the principles behind TVS – Varistors. TVS – Varistors are non-linear resistors that can dissipate energy through non-linear conductance. That is, they exhibit higher resistance in response to an increase in voltage, thus limiting the current flow. As such, they are well suited to protect circuits from voltage transients that can occur due to ESD (electro-static discharge) or lightning strikes.

The circuit diagram above shows an idea of how the VC120630D650RP works. The MOVs are connected in parallel with the surge protective device, and consequently, the protection device is in series with the rest of the circuit. Over its operating range, the MOVs shunts the surge current at a voltage higher than the clamp voltage of the device. The presence of the MOVs increases the protection level of the device, preventing the voltage transient from travelling any further in the circuit.

In conclusion, TVS varistors like the VC120630D650RP are an important element in any surge protection system. It is specifically designed to provide protection against voltage transients due to ESD and lightning strikes. This component is well suited for applications requiring high-performance and reliability, such as those in automotive, medical, military, and hazardous locations. Its working principle is based on its non-linear conductance characteristics, which limit the current flow and provide circuit protection against voltage transients.
