The VDRS14G014BSE (VDRS14G) is a common voltage varistor, which is widely used in a variety of applications. It belongs to the TVS (Transient Voltage Suppressor) Varistor, MOV (Metal Oxide Varistor) families. This device has many characteristics that make it highly suitable for a range of applications.

In common practice today, VDRs14G varistors are used to provide overvoltage and short-circuit protection in applications such as voltage regulators, battery chargers, overvoltage protection circuits, and automotive circuit protection. It is a key component in providing safety against overvoltage or high energy transients. The device also has a wide frequency response, high capacitance, and low leakage current; these features make the device very suitable for RF applications, including antenna and high-speed signal conditioning.

The working principle of the VDRS14G can be explained as follows. At normal operating conditions, the varistor has a high resistance, thus it provides the normal resistive load to the circuit. When a transient voltage or overvoltage magnitude is applied to the circuit, the varistor\'s resistance decreases significantly and a significant portion of the current starts to flow through the varistor, this provides a clamping effect as the overvoltage is clamped to a safe voltage. In this way, the protection from voltage transients is provided by the VDRS14G.

The clamping voltage range of a VDRS14G is typically in the range of 2.5 to 30 volts. The allowable surge current from a VDRS14G is usually in the range of 10 – 20 amperes. Its direct current voltage rating is usually 15 volts. Its capacitance is usually between 47-51pF. Its frequency response is typically in the range of 6.5MHz to 100MHz. Furthermore, the device has a low leakage current usually in the range of 10uA – 100uA.

Overall, due to its superior characteristics, VDRS14G varistors are used in multiple applications such as voltage regulators, battery chargers, overvoltage protection circuits, automotive circuits protection, and RF applications. The device provides excellent overvoltage or short-circuit protection, making it an ideal device for a variety of applications.
