TVS - Varistors, MOVs

Introduction

Transient voltage suppressors (TVS) are devices that protect electrical systems from high voltage transients. They are most commonly known by their commercial names: varistors, MOVs, and metal oxide varistors (MOV). TVS’s provide a layer of protection that absorbs and dissipates transient energy during unexpected voltage surges. When the voltage exceeds a predetermined limit, the TVS limits overvoltage, allowing the electrical system to operate as normal.

Insulation

TVS’s are effective because they provide insulation between the power supplies and the equipment or the line. This insulation helps prevent power fluctuations, as TVS’s protect against overvoltages, and provide electrical isolation. This ensures the safe operation of any electrical equipment—preventing both electrical shock and damage.

B72241L0231K100 Application Field and Working Principle

The B72241L0231K100 is a bi-directional, non-polar transient voltage suppressor (TVS) with a clamping voltage of 12V and a maximum peak amperage of 1A. It is designed to protect voltage sensitive electronics in a wide variety of applications, from telecommunications and automotive to computers and consumer electronics.The B72241L0231K100 is a three-terminal device used to protect against transient voltage spikes. It works by providing insulation between the power supply and the equipment or the line. This insulation helps protect against overvoltage, allowing the electrical system to operate safely and correctly.When a transient voltage spikes occur, the B72241L0231K100 acts quickly to absorb and dissipate the energy. It is important to note that the device has two clamping levels— the first level absorbs most of the energy and the second level clamps the remainder of the energy that may damage the sensitive components.The device also offers superior electrical noise immunity, excellent suppression capabilities and high peak power handling capacity. This makes the B72241L0231K100 an ideal choice for applications that require efficient, reliable and effective protection against high voltage transients.

Conclusion

TVS’s are essential devices for preventing and guarding against electrical fluctuations, transients, and overvoltage. The B72241L0231K100 is a versatile, bi-directional, non-polar TVS, which provides reliable, effective protection from high voltage transients. It offers superior electrical noise immunity, excellent suppression capabilities and high peak power handling capacity, making it an ideal device for a wide range of applications.
