TVS - Varistors, MOVs, are commonly used in electronic circuits, and play a critical role in protecting components from the destructive effects of overvoltage transients. The B72241L0421K100 is an example of such devices, used for protection against high-energy transients, and is typically used in AC, DC and signal line applications. This article will explore the application field and working principle of the B72241L0421K100

The overall construction of the B72241L0421K100 is similar to other two-port varistors, consisting of cores, encasing, and common electrode connections. These components are connected together in a series-parallel arrangement. The core consists of a ceramics material designed to provide a low resistance path to the overvoltage, whilst, at the same time, dissipating the energy of the transient in a controlled manner.

The varistor can be used in both AC and DC applications. In AC applications, the device is connected in series with the AC line, thus diverting the current away from other components, thus providing protection against overvoltage transients. In DC applications, the device is typically connected in parallel with the DC line, thus allowing the excess current to bypass the other components, thus protecting them.

The B72241L0421K100 varistor is also designed to protect against high-energy transients, such as those caused by lightning strikes or electrostatic discharges. The device will absorb large amounts of energy, allowing it to dissipate the energy safely through its structure. The device is designed to provide a low resistance path to the incoming surge current, allowing the device to conduct the surge and thus dissipate its energy. The device can also be used in signal line applications, where it is used to filter out spurious signals.

In addition, the B72241L0421K100 varistor is designed to be used in close proximity to other components, often mounted directly on top of the component. This close coupling allows the device to protect the components from the effects of overvoltage transients, by limiting the propagation delay, thus isolating the components from the source of the surge.

The B72241L0421K100 varistor has a wide application field, as it is designed to protect against both AC and DC applications, as well as high-energy transients and signal line applications. In addition, the device has a low capacitance and robust construction, meaning it is a reliable and long-lasting option for applications requiring transient protection.
