TVS (Transient Voltage Suppressor) Varistors, MOVs (Metal Oxide Varistors) are commonly used protection components in the field of electronic engineering. B72207S0151K311 is a varistor manufactured by Bourns and is used as an over-voltage protection device. It is designed for use in high-voltage applications such as high voltage DC-DC converters and telecom equipment. Its protection range varies from 400V to 450V when the rated voltage is 7.2KV.

B72207S0151K311 is a nonlinear, negative coefficient, solid-state device that works by providing a low-resistance path for overvoltage surges. It is typically a two-terminal device, with one terminal being the common ground and the other being the input/output. The two terminals are connected to a resistor through which the current flows. The resistor has a typical resistance of 12 ohms.When the voltage is above the breakdown voltage, the varistor will provide a low-resistance path for the surge current.

In operation, the device is designed to clamp transient voltages up to a maximum breakdown voltage, Vbr. At the same time, the dissipation energy of the device is limited, to prevent the device from overloading and damage. For common applications, B72207S0151K311 offers protection from overvoltages up to 450V with a breakdown voltage of 7.2KV. It also has a maximum rated current of 10A and a maximum non-repetitive peak surge current of 200A.

The main advantages of using the B72207S0151K311 varistor is that it is low in cost, fast response time, low leakage current, and robust construction. The varistor is also designed to be highly reliable with an UltiniyPlusT M uniform and low chance of short-term premature failure. As such, the B72207S0151K311 varistor is widely utilized in many high voltage applications to ensure safe operation.

In conclusion, the B72207S0151K311 is a varistor manufactured by Bourns which is capable of providing effective overvoltage protection in high voltage applications, such as high voltage DC-DC converters and telecom equipment for safe operation. It is a two-terminal device with a breakdown voltage of 7.2KV, a maximum rated current of 10A and a maximum non-repetitive peak surge current of 200A.
