The B72220T500K901V57 is a leaded varistor from TDK Corporation, designed for transient voltage suppression (TVS). Varistors are voltage-dependent resistors that exhibit a high resistance at normal operating voltages but a drastically reduced resistance when subjected to transient overvoltages, such as those caused by lightning strikes or inductive switching. They divert the excess current away from sensitive components, protecting them from damage.
