TVS - Varistors, MOVs

Varistors, known more formally as voltage-dependent resistors, combine characteristics of both a resistor and a diode. A varistor is an electronic component with a variable, non-linear resistance. It behaves like a resistor whose resistance can be vastly influenced by the applied voltage. A MOV, meanwhile, acts as a voltage dependent resistor that is easily able to dissipate large amounts of energy many times above its normal rated limits. By their very nature, varistors and MOVs work well to protect electrical and electronic circuits from overvoltage transients.

B72510V2170K72 is a new type of varistor marketed by Weiden Ltd. This series of varistors features improved stability against external temperature and humidity. It provides enhanced dissipative ability due to its high surge current rating. The B72510V2170K72 is mainly designed for use in circuit protection applications.

Application Field & Working Principle

The B72510V2170K72 can be used in a variety of applications. It has been successfully applied in the automotive and industrial markets, where it is widely used for protection in automotive electronic control units. It\'s also suitable for surge suppression in domestic appliances such as washing machines, dryers, cookers, televisions, computers, phones, and audio equipment. Additionally, it is perfect for safeguarding against lightning strikes, electrostatic discharge events, and various other transients.

The working principle of the B72510V2170K72 is fairly straightforward. When an abnormal voltage is detected, the varistor of the product instantly activates, dissipating the excess energy to the connected power and ground lines. Its non-linear resistive characteristics also form a “snubber circuit”, allowing the part to load the line with a low-impedance discharge path. This effectively acts to absorb very high-frequency transients, preventing them from damaging the connected circuits.

The B72510V2170K72 also offers several other features which make it a compelling option for circuit protection applications. For one, its advanced chip design means the device has an impressive life cycle, usually lasting 1 x 10⁷ or more. Additionally, its peak current rating is excellent, capable of withstanding huge surges well above its rated DC voltage. Lastly, its protection works both ways – it can clamp down on both low and high voltage.

Conclusion

The B72510V2170K72 is one of the most advanced varistors on the market today. It offers an unprecedented level of overvoltage protection, and its safety-related features endow it with a long-lasting lifetime. The device can be used in a plethora of applications, and its price is very competitive. All in all, the B72510V2170K72 is the ideal choice for circuit protection applications in the automotive, industrial, and domestic markets.
