B72210S1140K401 is an electronic component classified as a TVS (transient voltage suppressor), a type of Varistor (variable resistance) or MOV (metal-oxide varistor) product used to protect sensitive electronic circuits from voltage spikes.

TVS (transient voltage suppressors) are voltage-dependent, non-linear resistors which reduce the amplitude of an applied voltage when the voltage reaches a certain predetermined trigger value. This makes it an effective means of protecting against transient electrical incidents which cause voltage spikes. For this reason, TVS devices are used widely in the protection and control of electronics, and are found in electrical and electronic products such as computers, cell phones, LEDs, and many types of machines.

TVSs, Varistors, and MOVs all serve the same basic purpose–to reduce macro-discharges and micro-discharges, or parasitic oscillations, which can cause damage to an electrical device or system. Varistor products are essentially organic semiconductor varistors, made from a solid-state combination of metal oxide and semiconductor materials, which allow the component to rapidly switch electrical currents and rapidly dissipate voltages. MOVs (metal-oxide varistors) are similar to Varistors, but contain both a metal oxide and a dielectric material for an even stronger protection. These components are the most commonly used form of transient voltage suppression products.

The B72210S1140K401 is one of these components. It is a High-stability TVS, designed for applications where the voltage threshold is above 8V. It is a unidirectional TVS with a 141pF capacitance and 10kΩ resistance value. It features a low clamping voltage, high transient suppression capability, and a reverse leakage current of 0.1uA. And at 175°C, the B72210S1140K401 has a thermal resistance of 0.10°C/W and a maximum spike voltage of 11V.

The application field of B72210S1140K401 is broad and includes the automotive, industrial, and medical industries. It can be used to protect against over voltage and over current, protecting all electrical and electronic devices from transient voltage spikes. Some examples of applications include automotive power systems, LED lighting, industrial controls, medical electronics and diagnostic medical systems. The B72210S1140K401 is also used to protect against transient susceptibility of sensitive electronics due to direct lightning strikes, electrostatic discharge, voltage spikes, induced transients, and other transient protection issues.

The working principle of the B72210S1140K401 is relatively simple. When the voltage applied to the device reaches a certain threshold voltage, it will trigger the device to begin to reduce the voltage amplitude. This is done effectively and with very low losses thanks to the materials used and the construction of the component. It can handle peak transaction currents of up to 11V for a very short period of time which makes it very well suited to a variety of overvoltage, overcurrent and transient spike protection needs.

In summary, the B72210S1140K401 an electronic component classified as a TVS, Varistor, or MOV product used for protection from voltage spikes. It has a wide range of applications in the automotive, industrial, and medical industries. Its working principle is relatively simple: when the voltage applied to the device reaches a certain predetermined trigger voltage, the component triggers and begins to reduce the voltage amplitude with very low losses.
