Surge protective devices, such as Varistors, MOVs, and TVS, are essential components in many electronic circuits. As one of the most common and commonly used surge protective devices in electric equipment, VDRS05C250BSE plays an important role in protecting electronic circuits. This article will introduce the application field and working principle of VDRS05C250BSE.

Application Field of VDRS05C250BSE

VDRS05C250BSE belongs to the family of Transient Voltage Suppressor, which is mainly used for over voltage protection. It is often used in electrical systems where a huge amount of energy can be created from overvoltage surges, resulting in damage to the components. Its application fields include communication equipment, computers and remote control systems, automotive electronics, power electronics, nuclear industry and more.

The device can provide effective and reliable protection from overvoltage and its related problems. It is known for its ability to withstand large voltage spikes and control damage in circuits. The VDRS05C250BSE is suitable for use in circuits with AC or DC input and operates within a range of 1.7V to 28V. It has a low capacitance, high speed response, high peak power and low clamping voltage, and is a good choice for surge protection.

Working Principle of VDRS05C250BSE

The VDRS05C250BSE is built from a highly engineered silicon carbide junction which acts as an avalanche break-down region. This mechanism is triggered when the voltage increases beyond a certain threshold, resulting in conduction through the junction in an avalanche or zener-like fashion. The current paths between the anode and cathode are designed to absorb surplus energy in the form of a voltage spike and dissipate it before it reaches damaging levels.

When normal voltage conditions, the VDRS05C250BSE acts as an open circuit. As soon as the voltage reaches the breakdown voltage, current will flow through the device and act as a voltage regulator. The device regulates the voltage to a safe level by restricting the current flow. This results in limiting the voltage spike that would have caused damage to the circuitry. After the current has been dissipated, the VDRS05C250BSE reverts back to its open circuit state until the voltage rises again.

Conclusion

VDRS05C250BSE is a commonly used transient voltage suppressor device. It is used to protect electronic circuits from over voltage surges. It has a wide application range and is suitable for AC and DC input. Its main mechanism is the avalanche break-down region, which limits the voltage spike that would have caused damage to the circuitry. With its superior performance, VDRS05C250BSE can effectively protect electronic circuits from overvoltage.
