TVS (Transient Voltage Suppressors) are a type of semiconductor device that are designed to protect electronic circuits from voltage transients or high voltages. They provide a quick surge of current to divert damaging energy away from vulnerable circuits, allowing them to remain undamaged. Varistors, MOVs (Metal Oxide Varistors) and Silicone Avalanche(SAD) Diodes are all types of TVS devices, and each has its own application and working principle. In this article we will discuss the application field and working principle of one particular type of TVS, the Varistor VDRS20M035BSE.

The VDRS20M035BSE is a metal oxide varistor that is specifically designed for the suppression of overvoltages in AC power applications. It features low capacitance, low leakage and is designed to withstand voltages up to 1500V. This varistor is commonly used to protect AC power lines and is capable of dissipating up to 16A of surge current. It has a clamping voltage of 500V and a 56V operating voltage, making it an ideal solution for suppressing AC voltage transients.

Now let’s take a look at the working principle of this varistor. Essentially, the VDRS20M035BSE uses a metal oxide ceramic body to absorb energy from high voltage transients or overvoltage spikes. This ceramic body is formed from zinc oxide grains that are bonded together. When voltage passes through the varistor, the zinc oxide grains absorb the energy and convert it into heat, dissipating it away from the protected circuit. This is the basis of the working principle of the VDRS20M035BSE.

There are several advantages of using the VDRS20M035BSE compared to other types of TVS devices. Firstly, it is a very low-impedance device which means that it is able to suppress overvoltages very efficiently. Additionally, because it is designed for AC applications its dissipation factor is very high, meaning that it can dissipate high amounts of surge current with very low leakage. Furthermore, its thermal stability means that it is able to withstand very high voltages, including peak attacks, without damage.

In conclusion, the VDRS20M035BSE is a very efficient AC power line suppressor that is able to efficiently dissipate high surge currents. It features low capacitance, low leakage and high thermal stability, making it an ideal solution for protecting sensitive circuits from overvoltage spikes. Its working principle is based on the absorption and conversion of energy from overvoltages and it is able to withstand voltages up to 1500V. We hope that this article has given you some insight into the application field and working principle of the VDRS20M035BSE.
