The VDRS20W060BSE is a device that is part of TVS - Varistors, MOVs (Transient Voltage Suppression Devices). It is essentially a diode which protects electrical circuits from voltage spikes caused by electrostatic discharge (ESD), lightning, and other factors. The device helps to prevent potentially damaging electrical currents from reaching delicate circuit boards and other sensitive components. This is done by allowing the flow of current in only one direction, and then dissipating any excess voltage from the circuit.

The VDRS20W060BSE has two primary sections, the anode and the cathode, both of which are connected to a lead. The anode is connected to the most positive voltage source, while the cathode is connected to the most negative voltage source. Once connected, the device will begin to operate in either "on-state" mode or "off-state" mode, depending on the voltage across the terminals.

In the on-state mode, the device functions as a rectifier or diode, allowing current to flow through one direction only. This helps to protect the circuit from any sudden and damaging voltage spikes. On the other hand, in the off-state mode the device will not allow any current to pass, and this is part of its protection against ESD, lightning, and other sources of electrical disturbances.

The device is typically specified for ESD protection and has an IEC rating of 60. It also has a UL flammability rating of UL94V-0 and a maximum surge current rating of 60A. All these ratings are designed to ensure the circuit is adequately protected from the various types of voltage spikes. The device can work in many application fields, including computers, medical devices, and telecommunications.

The working principle of the VDRs20W060BSE is based on its construction of metal oxide varistors (MOVs). MOVs are composed of two layers of zinc oxide, with a terminal opening in between them for current to pass through. During normal operation, the MOVs allow only a small amount of current through, but when voltage spikes occur, the current will be diverted and routed through one of the layers. This will cause the MOVs to change shape and expand, allowing more current to be diverted. This expansion will also help to reduce the spike\'s voltage and protect the circuit from damage.

Overall, the VDRS20W060BSE is a device that can provide effective protection to electronic circuits from voltage spikes. It utilizes the principles of MOVs, and its specified ratings help to ensure adequate protection is provided. The device can also be used in a range of different applications, making it a handy and versatile tool for various projects.
