TVS (transient voltage suppressors), varistors, and MOVs (metal oxide varistors) belong to the same overall family of products which are used for over-voltage and over-current problems. As such, they have some very important characteristics in common. All of these devices are designed to intercept electrical transients in order to protect the circuits in which they are installed. Each device accomplishes this task in a slightly different way. This article will explore the application field and working principle of the V120ZU6 varistor MOV.

The V120ZU6 is a medium-power varistor MOV with a voltage rating of 700 volts and a current rating of 100 amps. The device can serve as an over-voltage/over-current protection device in AC or DC power circuits, as well as EMI (electromagnetic interference) filters. The V120ZU6 has a response time of 10 nanoseconds or less in order to effectively suppress both conducted and radiated EMI. When used as an EMI filter, the device can provide a frequency range of up to 10 MHz.

The working principle of the V120ZU6 involves three stages. First, the device intercepts the electrical transient and diverts it away from the protected circuits. This is accomplished by the device’s specific insulation resistances, which form an electric barrier between the transient and the other circuits. Secondly, the device dissipates the energy of the intercepted transient, dissipating it as heat. Thirdly, the device limits the amount of energy transfer to the protected circuits. This is ensured by the device’s capacitance value.

The V120ZU6 is designed with several key features that make it suitable for use in power and/or EMI applications. The device has a low clamping voltage and a high surge current capability which makes it well-suited for protecting sensitive, low-voltage circuits from transients. Additionally, the device has a long lifetime due to its high peak current rating. Finally, the device has a wide temperature range, making it suitable for use in a variety of environments.

The V120ZU6 is an excellent choice when it comes to Power and EMI applications. It is well-suited for protecting low-voltage circuits from transients, while also providing a broad frequency response for EMI filtering applications. By incorporating three separate stages into its construction, the device is able to intercept and dissipate transients in an effective and reliable way, allowing it to provide long-term protection from EMI and other power issues.
