Varistors, also known as voltage dependent resistors (VDRs), are passive, electronic components with a highly nonlinear current-voltage response. They are most commonly used for transient protection, surge mitigation and noise reduction. The B72280B0131K001 is a varistor device produced by EPCOS, a manufacturer of electronic components. This device is a high-reliability, three-terminal voltage protection device that provides both overvoltage and overcurrent protection against destructive transients.

The B72280B0131K001 is a type of metal oxide varistor (MOV), which is made up of a ceramic body containing a mixture of zinc oxide and other metal oxides. The MOV absorbs low, normal, and high levels of voltage and redistributes it to the ground. The redistribution of the voltage helps protect the circuit from overvoltage and overcurrent conditions. This is accomplished through the non-linear rate of current flow versus voltage.

When applied up to its clamping voltage, the B72280B0131K001 varistor absorbs and disperses a large amount of energy within a short amount of time. When the voltage reaches its minimum breakdown voltage, the varistor will conduct current, redirecting power away from the circuit and into a fusing device. If the current reaches a certain threshold, the MOV will absorb the current and limit the voltage across the device by emitting heat.

The B72280B0131K001 is typically used for transient protection. It can limit overvoltage events, thereby protecting against possible electrical and thermal damage, and it can also minimize the power dissipated in the power supply circuit. This varistor is suitable for protecting components and systems such as computers, peripherals, communication systems, and LED lighting applications.

In addition, the B72280B0131K001 features a low clamping voltage with a high peak current capacity. Its low voltage and high current capability make it ideal for protecting systems using low operating voltages, such as microprocessor-based equipment, as well as devices with low voltage supplies, such as personal computers, appliances, and digital televisions.

In summary, the B72280B0131K001 is a high-reliability, three-terminal voltage protection device that provides both overvoltage and overcurrent protection, making it ideal for protecting components and systems from destructive transients. This MOV has a low clamping voltage with a high peak current capacity, making it suitable for low operating voltages. Its ability to absorb and disperse energy makes it an excellent choice for applications that require transient protection.
