TVS - Varistors, MOVs, are elements used to protect systems from too high voltages. Designed to those specifications, the ROV20-101K stands for a very special application field and working principle.In order to understand the working principle of the ROV20-101K, it is necessary to first have an overview of what TVS - Varistors, MOVs in general and what they are used for.TVS - Varistors, MOVs, are resistors specifically designed to protect sensitive circuits and components from too high voltages. Their use applies in electrical circuits when an abnormal steady voltage above its working voltage appears, the MOVs limit this voltage so that it does not cause any damage.To provide this protection, these devices must work within a tight range of tolerances. These tolerances are expressed in terms of working voltage (V SW ) and holdover voltage (V HSL ). Depending on the specific application, these elements must be chosen accordingly in order to provide the most optimal protection.The ROV20-101K is a specific MOV that is especially designed for filtering and protecting sensitive analog circuits from too high voltages. It is designed to the specific requirements of these applications and to provide the optimal protection. It has a rated voltage of 600V and a current carrying capability of 20A. This makes it ideal for filtering and protecting sensitive analog circuits.The working principle of the ROV20-101K is very simple. It works by monitoring the voltage level present in the circuit and responding by reducing the voltage to a safe level. This is done through the use of a highly specialized reverse-biased diode, which redirects current to a pre-specified level and prevents damage to the sensitive elements in the circuit.When the voltage level reaches the working voltage (V SW ), the diode conducts the excessive current and reduces it to a safe level. The excess current is then diverted through a shunt or through an external resistor and effectively dissipated.Likewise, when the voltage level exceeds the holdover voltage (V HSL ), the diode will start to conduct the excessive current and reduce it to a safe level. Again, the excess current will be diverted, this time through an external drain, and effectively dissipated.In conclusion, the ROV20-101K is an ideal device for protecting sensitive analog circuits from too high voltages. Its design is specifically tailored to these applications and its working principle is extremely effective in providing the necessary protection. This makes it the perfect choice for protecting sensitive circuits and components.
