TVS - Varistors, MOVs

The B72210S0681K351 is an example of a transient voltage suppressor. Transient voltage suppressors are used to protect sensitive electronics such as microprocessors, memory chips, and other semiconductors from voltage spikes and high-voltage transients. The B72210S0681K351 is an unidirectional device designed to clamp voltage up to 14 volts.

The B72210S0681K351 offers high-quality protection from overvoltage conditions, such as the very common transient voltage spikes caused by inductive loads or other electrical disturbances. It is constructed of metal oxide varistors (or MOVs), which are monolithic chips of materials that are designed to block the flow of current when the voltage exceeds a certain level. MOVs are found in many devices, including power supplies, surge protectors, and automotive electronics. The B72210S0681K351 has a peak pulse current rating of 400A 8/20μs, and a clamping voltage of 15.1V.

B72210S0681K351 can be found in a number of applications, from commercial and general-purpose circuit protection to automotive and aerospace applications. It is used to protect equipment from electrical disturbances caused by lightning, switching transients, or electric motors starting. It is also used to protect against overvoltages and power outages. In addition, it can be used in low-voltage DC power supplies, as well as in the protection of digital I/O ports.

The working principle of the B72210S0681K351 is based on the concept of varistor action, which occurs when the applied voltage reaches a threshold, causing the MOVs to become highly conductive. When this happens, the MOVs draw a large current, which creates a voltage drop and limits the peak voltage at the output. This prevents damage to the protected devices by limiting the voltage spike.
