VRS0402SR55R101N is a chip-based varistor device made by Changxin Electronic Technology. It is a type of TVS – Varistors, MOVs that is primarily used for applications that require transient overvoltage protection in order to extend the life of a product. This device is able to provide transient voltage suppression with peak pulse energy dissipation capabilities as high as 67 Watts @ 8 / 20µs time constant.

Transient voltage suppression (TVS) devices, also known as Varistors, MOVs or Transil, are a type of surge protection device which helps to protect circuits from extreme overvoltage transients such as lightning strikes or other external disturbances. VRS0402SR55R101N suppress transients by clamping low energy levels that would otherwise cause damage to system circuitry. This is achieved by allowing a high voltage to be passed through a low resistance path, thus providing a current path for the transient to prevent dangerous surge levels reaching the protected circuit.

The working principle of VRS0402SR55R101N involves a low leakage current blocking reverse bias diode which has a relatively high breakdown voltage. The breakdown voltage of the varistor is determined by the amount of current flowing through its terminals. When a voltage great enough to exceed the breakdown voltage is applied, current will begin to flow. This current flow causes the diode to clamp the voltage at the breakdown voltage. This clamping of voltage prevents any further voltage from reaching the protected component or circuit. This is how VRS0402SR55R101N provides a low impedance path for transients and prevents further damage to the protected components.

The VRS0402SR55R101N can be used in a variety of applications that require overvoltage protection. These applications range from automotive and industrial control systems to personal computers. This device is also suitable for applications such as power supplies, communications systems, and audio systems. Additionally, this varistor is able to withstand short high voltage pulses as well as EFT or ESD transients.

The VRS0402SR55R101N the device is able to provide superior transient protection due to its high peak pulse power. It is also designed with an integrated ring core package which improves its mechanical strength and electrical insulation, allowing it to perform well in harsh environment conditions. This package provides additional advantages including low insertion voltage, operating temperature range, and size.

The VRS0402SR55R101N device, along with its numerous advantages, makes it an ideal overvoltage protection solution for a large variety of applications. Its high temperature and fast-switch capability make it perfect for applications with high power demands, while its small size makes it ideal for applications that may have limited space requirements. Additionally, its integrated ring core package provides enhanced stability and insulation, making it suitable for harsh environment applications such as automotive and industrial electronics.
