The B72214S2421K551 is a device designed for protection against transients and surges in applications such as automotive, commercial, domestic and industrial. The device has a working voltage of 6 to 24 Volts and a protection capability of 10 A. It is generally used in static battery protection against overvoltage and transients.

This type of transient-voltage-suppressor (TVS) is typically a zinc oxide-based varistor, which is a semiconductor-type component specifically designed for protection against voltage transients and surges. A varistor has a voltage-dependent nonlinear electrical property that enables it to act as an active, non-linear device, dedicated to suppressing transient voltage spikes.

When the voltage across the two terminals of the device reaches a certain undefined point, the device shifts from a high-impedance state into a low-impedance, or conducting, state. This change in impedance “blocks” the surge current from passing through the device. Thus, the varistor acts as a shield, protecting the circuitry against the effect of large-scale surges.

TVS devices are also known as metal-oxide varistors (MOVs). an MOV is a type of circuit-protection component. It is an electronic component that serves to absorb excess electrical current that may be passed through it due to a surge of electrical energy.

An MOV contains a zinc oxide disc and an opposite “tap” that are connected to two electrical terminals. It works by temporarily diverting electrical energy or current to avoid damage or breakage of the electrical components. It is used in computers, television sets and fax machines, among other electronic devices and systems, for transient-voltage suppression.

By employing an MOV device to absorb much of the surge energy, system arrays, power lines, and other large electrical structures can protect themselves from the effects of other nearby electrical discharge or inductive loadings. This protection mechanism is essential to the safe running of many electrical systems.

The B72214S2421K551 is a versatile and robust device that protects against surge-induced shorts in TV sets, PC systems, automobile electronics, fax machines and other consumer electronic products. With its advanced technology and efficient design, the B72214S2421K551 is ideal for nearly all transient-voltage-suppression needs.
