The B72650M0251K072 is a TVS - Varistors, MOVs (Metal Oxide Varistor) device consisting of a network of two or more Nonlinear Resistors (Varistors) connected in parallel with the lead frame inside a plastic casing. The device is often used for protection against surges in electrical currents in a wide variety of consumer, commercial, and industrial applications. The working principle of the B72650M0251K072 device is to provide a low resistance path for transient overvoltage or overcurrent, while providing high impedance to normal operating voltage or current. It helps to protect electronic components from overvoltage and overcurrent caused by electrical surges or electrical disturbances.

The B72650M0251K072 is mainly used to protect electronic components from overvoltage and overcurrent caused by sudden high voltage surge or transient. It is widely used in consumer, commercial, and industrial systems, such as aviation, automotive, military, communication, electrical equipment, lighting and computer fields. The primary application of the B72650M0251K072 is transient suppression for DC and low frequency AC voltage ranges. It is also widely used in the protection of electronic systems against surge voltages caused by lightning, static electricity, power switching, and ground faults. In addition, the B72650M0251K072 can be used for EMI/RFI noise reduction, switching suppression, and frequency dependent transient protection.

The B72650M0251K072 has a very distinctive structure. It comprises two terminals, one is called the “fixed” terminal and the other is the “wire” terminal. The fixed terminal is made of metal oxide film, and the wire terminal is made of copper wire. The two terminals are connected with electrodes at their respective ends. Inside the device, the metal oxide film is the principal part which performs its transient voltage suppression tasks. Its inner layer consists of negatively charged non-linear resistors or Varistors. The copper wire provides contact with the electrical circuit and enables the transfer of the charge signal to the device.

The working principle of the B72650M0251K072 follows the basic rule of voltage breakdown. When the voltage drop across the device terminals reaches a certain voltage level, the current induced by the voltage breakdown increases and exceeds the rated current of the device. This current breakdown causes the metal oxide film to break down, creating a path for the current. The current then dissipates through the non-linear resistor, thereby reducing the voltage drop across the device. The B72650M0251K072 also has a voltage clamping capability, which helps to reduce the voltage during a transient voltage surge.

Apart from its aforementioned voltage and current breakdown capabilities, the B72650M0251K072 is also designed to offer EMI/RFI noise reduction, switching suppression, and frequency dependent transient protection. The device works by absorbing the EMI/RFI noise, which then dissipates through the non-linear resistors. The frequency dependent transient protection helps to reduce the transient voltage when it is below a certain trigger voltage, thus avoiding circuit damage caused by overvoltage and overcurrent.

The B72650M0251K072 is a versatile device, suitable for a wide range of applications. It is used to protect electronic components from overvoltage and overcurrent caused by electrical surges or electrical disturbances, and also for EMI/RFI noise reduction, switching suppression, and frequency dependent transient protection. With its low insertion loss and high surge current capability, it is a reliable and cost effective solution for a variety of consumer, commercial, and industrial systems.
