TVS-Varistors, MOVs, are one of the most commonly used components in electrical and electronic engineering. They are used in a variety of different applications, from audio electronics to protection against overvoltage surges. The B72220P3681K101 is a Varistor-MOV (Metal-Oxide Varistor) that offers protection against these transient overvoltage surges, serving to protect the circuit from overvoltage damage or destruction.

The B72220P3681K101 is an automotive grade, non-polar Varistor with a minimum breakdown voltage of 510V. This Varistor-MOV is primarily used in automotive applications, such as controlling power supply surge protection of Auto-Mobiles & portable electronic components. It has a standard thickness of 0.6mm (±0.1mm), allowing it to fit in small and complex spaces that many other protection devices cannot. In addition to automotive use, the B72220P3681K101 can also be used in any industrial application, as a reliable protection device against sudden overvoltage surges and ESD transient surges.

The workings of Varistor-MOVs can be explained with a few basic electrical principles. When an electrical overvoltage surge occurs, it increases the electrical potential across the Varistor-MOV. This increased potential is what triggers the Varistor-MOV to conduct, thereby limiting the voltage that can reach the circuit. The Varistor-MOV has an electrical resistance that increases as the voltage applied to it increases. This property allows it to “absorb” a certain amount of the overvoltage before letting it pass to the circuit, thereby protecting the circuit from its destructive potential.

Varistor-MOVs, such as the B72220P3681K101, are designed to protect electronic circuits from transients caused by excessive voltage spikes. Transients can range from extremely brief (a few microseconds) to extended periods up to milliseconds or even longer. Varistor-MOVs also offer protection against ESD (electrostatic discharge). Furthermore, they are usually manufactured with integrated thermal protection, making them a safe and reliable protection option against various issues caused by overvoltage transients.

The B72220P3681K101 Varistor-MOV is an ideal protection device for various automotive and industrial applications. Its small, lightweight construction is perfect for fitting into complex and difficult to reach spaces, and its excellent protection capabilities make it well-suited for protecting against overvoltage transients. This Varistor-MOV offers reliable, cost-effective protection against damaging electrical overvoltage transients and ESD, making it a common choice for use in automotive and industrial applications.
