TVS - Varistors, MOVs are protective devices that are used in electrical circuits to protect sensitive electronic components from damage caused by high voltage transients and electrical noise. The VDRS05C350TSE is a type of varistor that is designed for use in telecom and power line applications. It has a high surge capability of 5 kA (8/20 μs), a working voltage range of –35 VDC to 35 VDC, and a breakdown voltage of 350 VDC.

A varistor is an electronic device that consists of a network of elements connected in series and is designed to be non-linear so that it has a specific Voltage vs. Current, or V-I curve. This type of varistor is commonly referred to as a Metal Oxide Varistor (MOV). The MOV has a high impedance at low voltages and offers low resistance at higher voltages. The VDR05C350TSE has a V-I curve that is designed to allow the current to flow in the opposite direction when the voltage exceeds its breakdown voltage.

The purpose of using a VDR05C350TSE is to protect a circuit from overvoltage and surges. When the voltage reaches a certain level, the voltage across the varistor is limited to its rated breakdown voltage. This allows it to absorb enough energy to protect sensitive components from excessive voltage. The VDR05C350TSE is also designed to dissipate all stored energy when it is not subjected to high voltage surges, thus minimizing residual energy in the system. It also helps reduce electromagnetic interference (EMI) and increase system stability.

The VDR05C350TSE can be used in a variety of applications, including telecom, automotive, and power line. In a telecom application, it can be used to protect equipment from overvoltage and transients caused by line frequency disturbances. In an automotive application, it can be used to protect electronic components from high voltage spikes caused by lightning strikes. In a power line application, it can be used to protect sensitive electronic equipment from high current surges caused by the switching of inductive or capacitive loads.

The working principle of the VDR05C350TSE is relatively simple. It consists of a network of metal oxide components that are connected in series. When a voltage greater than the rated breakdown voltage is applied across the varistor, the voltage is limited to the breakdown voltage, and the current is diverted around the network. This helps to protect sensitive components from overvoltage and transients. It also dissipates any energy that is stored in the system after it has been subjected to a high voltage surge.

In conclusion, the VDR05C350TSE is a type of Metal Oxide Varistor that is designed for use in telecom and power line applications. It has a high surge capability and a working voltage range of -35VDC to 35 VDC. Its V-I curve is designed to divert current around the network when the voltage exceeds its breakdown voltage, thus limiting the voltage across the varistor. It is also designed to dissipate all stored energy and reduce EMI when it is not subjected to high voltage surges. The VDR05C350TSE is suitable for use in telecom, automotive, and power line applications.
