TVS - Mixed Technology

Transient voltage suppressor (TVS) is a commonly implemented technology that is designed to protect devices from high current and voltage events on an electrical circuit. TVS technology can be implemented using several different approaches, each with its own advantages and drawbacks. This article will explore the general concept behind the TVS technology, its application fields, and its working principles.

Overview of TVS

TVS protection technology has become an integral part of many electrical circuits, as it can protect circuits from faults, surges, transients, and other unplanned events. It is designed to operate like a fuse - once the voltage or current exceeds a certain threshold, the device is immediately activated and quickly dissipates the energy. The advantage of this technology is that it is extremely fast-acting, providing greater protection than traditional fuses.The basic principles behind TVS technology are relatively simple - when a high voltage or current is applied to the device, it activates an internal protection circuit. This protection circuit then dissipates the energy, either as heat or by redirecting it away from the protected circuit. This ensures that the device is not damaged, and that the device continues to function properly.

Application Fields

TVS technology is used in a wide variety of application fields, ranging from automotive systems to consumer electronics. In the automotive industry, TVS devices are used to protect vehicles from high-voltage transients caused by an electrical spike or surge. This ensures that the vehicle’s electrical system remains stable, even during times of high voltages. In consumer electronics, such as televisions and computers, TVS technology is used to protect the sensitive components from damage due to voltage or current changes. In the industrial sector, TVS devices are used to protect equipment and circuity from high-voltage transients. In factories and industrial plants, TVS devices are used to protect motors, circuit boards, and power supplies from unexpected high-voltage events. This ensures that the equipment is not damaged, and that the plant can remain operational.

Working Principle

The working principle of a TVS is relatively straightforward - when a voltage exceeds a certain threshold, usually between 6V and 7V, the device activates a protection circuit. This protection circuit then dissipates the energy, either as heat or by redirecting it away from the protected circuit. As mentioned earlier, this ensures that the device is not damaged, and that the device continues to function properly. The amount of voltage and current that the device is able to dissipate depends on its size and design. For example, a small-sized TVS device may only be able to dissipate a few volts or amperes, while a larger-sized TVS device may be able to dissipate a much higher voltage and current. Additionally, some TVS devices may be designed to activate at a different threshold or to provide a different level of energy dissipation.

Conclusion

TVS technology is a versatile and reliable form of protection that can be used in a myriad of applications. It is designed to provide fast-acting protection, dissipating voltage and current when it exceeds a certain threshold. This ensures that the device remains undamaged, and that the electronics remain operational. TVS technology can be found in automotive, consumer electronics, and industrial applications, providing protection from high-voltage transients and surges.
