TVS - Varistors, MOVs are a series of voltage dependent protective components often used in electronic systems for mitigating ESD and surge attacks and protecting equipment from electrical surge or transient voltages. The VDRS07H060BFE belongs to this series and has a wide application in various types of electronic equipment. This article will discuss the application field and working principle of the VDRS07H060BFE.

The VDRS07H060BFE Varistor is designed for surge protection applications up to 15 KV. It is most commonly used for protecting AC/DC power supplies, telecom systems, industrial control systems, consumer electronics and communication equipment from electrical surges. This device is capable of absorbing up to 600 volts of electric surge or transient voltage, making it an excellent choice for protecting delicate components and systems from damage due to high voltage surges or transients. It is also suitable for protecting equipment from voltage over-voltage and short circuit conditions.

The VDRS07H060BFE is a non-linear multi-layer ceramic metal oxide varistor (MOV) made up of several layers of ceramic plates coated with zinc oxide (ZnO) semiconductor material. As an MOV, the VDRS07H060BFE is designed with high dielectric strength to ensure many years of reliable operation. The VDRS07H060BFE also offers a low leakage current and a low leakage inductance, making it an ideal choice for high frequency applications.

The VDRS07H060BFE works by providing a variable and non-linear resistor between ground and an over-voltage event. In the presence of an over-voltage event, the VDRS07H060BFE will conduct current between ground and the over-voltage source in order to reduce the transient voltage and protect the system or equipment from damage. As the voltage increases, the resistance of the VDRS07H060BFE will decrease and allow more current to flow through it, thereby reducing the surge or transient voltage.

Additionally, the VDRS07H060BFE features a built-in thermal protection mechanism which provides thermal protection against possible damage. The thermal protection mechanism prevents the VDRS07H060BFE from overheating due to prolonged exposure to excessive surge or transient voltages. If the MOV overheats, the thermal protection mechanism will shut off the current flow to the MOV, protecting downstream circuits from possible further damage.

The VDRS07H060BFE also includes a Resistance-Temperature (RT) coating on the surface, which adds additional temperature protection and allows for greater current carrying capacity. The RT coating helps to dissipate heat and protect the MOV during temperature cycles. This helps improve the reliability and long term performance of the VDRS07H060BFE.

Overall, the VDRS07H060BFE Varistor is an excellent choice for surge protection applications up to 15 KV. It is capable of absorbing up to 600 volts of electric surge or transient voltage, making it an excellent choice for protecting AC/DC power supplies, telecom systems, industrial control systems, consumer electronics and communication equipment from electrical surges. It also offers a low leakage current and low leakage inductance, making it ideal for high frequency applications. Lastly, the built-in thermal protection mechanism and the RT coating further enhance the reliability and long term performance of the VDRS07H060BFE.
