Transient Voltage Suppressors (TVS) are protective electronic components designed to protect other components in a circuit from overvoltage. The B72214S2421K101 is a surface-mount, varistor-type TVS that operates over a voltage of 12-24V.
Application Field
The B72214S2421K101 is a surge protective device designed primarily for use in automotive and industrial electronics applications that require protection from transient over-voltage, transient under-voltage, surge, and ESD protection. It has a clamping voltage of 18V, and a maximum surge current rating of 1A. This makes it suitable for use in automotive, industrial, and consumer device applications, such as DC-DC converters, DC-AC converters, power supplies, LED lighting, and other electrical and electronic applications.
Working Principle
The B72214S2421K101 is a Metal-Oxide Varistor (MOV) device, meaning that it operates using Voltage Dependent Resistor (VDR) technology. In essence, it has two electrodes: a cathode and an anode. When a voltage, greater or lesser than the rated voltage range, is applied to the electrodes, a voltage across them creates an electrical field. The electrical field polarizes the electrical particles within the media of the MOV device. Eventually, this polarization reaches a tipping point, and the electrons and ions in the media break down, forming a conductive path. This conduction, most of which occurs very quickly, redirects the excess energy, allowing it to be dissipated in the form of heat.
Conclusion
The B72214S2421K101 is a versatile and robust surge protective device designed for use in a wide range of automotive and industrial devices. It has a clamping voltage of 18V, a maximum surge current rating of 1A, and operates over a voltage range of 12-24V. By using VDR technology, it is able to quickly and efficiently dissipate the excess energy caused by overvoltage and undervoltage conditions, providing reliable protection for connected components.
