TVS (Transient Voltage Suppressor) diodes are an important component for providing over-voltage protection. Varistors, MOVs (Metal Oxide Varistor) and VDRs (Voltage Dependent Resistor) are the three main components in the TVS family, and they provide electrical protection for power systems, control systems, medical equipment and other electronic circuits. One of these components is called a VDRs10P385BSE, which is a voltage-dependent resistor that is used for over-voltage protection in ac applications with various protection levels.

The VDRs10P385BSE is a metal oxide based VDR that is commonly used in ac applications, as it offers a high reliability for circumstances that require a large level of over-voltage protection. The resistor is available with multiple surge protection level options, up to a maximum of 10,000 volts. It is constructed with structured silicone, and its electrical characteristics remain stable over a wide temperature range. The product has a minimum resistance of 0.1 mΩ, a maximum capacitance of 100 pF, and a highly reliable dielectric withstanding voltage of 25,000 V.

The VDRs10P385BSE application field mainly include ac power systems, communication systems, automation systems, medical systems, audio/video systems, automobile systems, and other electronic circuits. It has also been broadly used for in-vehicle electronics and aircraft guidance equipment. The device can provide over-voltage protection by clamping transient voltage generated by a lightning strike or other electrostatic discharge for electronic circuits.

The operating principle of the VDRs10P385BSE is based on the breaker function. When the voltage applied to the device reaches the specified level, the device limits the maximum value of the applied voltage. When a surge occurs, the device conducts the over-voltage to ground and prevents the circuit voltage from rising further. It is important to choose the most suitable VDR for the specific circuit in order to provide the required protection, as there are different VDRs with different characteristics.

VDRs offer some advantages over other TVS components. Varistors and MOVs are typically used for general-purpose protection, while VDRs offer additional features such as high peak current handling capability and superior thermal response to high current transients. Additionally, VDRs exhibit a low leakage current, making them suitable for low-power and low-voltage applications.

In conclusion, the VDRs10P385BSE is a voltage-dependent resistor that is used for over-voltage protection in ac applications with multiple protection levels. This device is specifically designed for applications such as ac power systems, medical systems, automobile systems, and aviation systems. It operates by limiting the maximum level of the applied voltage, and is advantageous due to its low leakage current and high peak current handling capability.
