TVS - Diodes

The JAN1N6120A is a type of transient voltage suppressor diode, or TVS – diodes, which are protective components used to protect sensitive electronic components from transient voltage and turn on quickly for overvoltage protection. TVS diodes are used to protect sensitive components and circuitry from voltage spikes caused by electromagnetic interference (EMI) and electrical fast transients (EFT). They are also used to prevent the backflow of capacitor-stored energy, as well as provide over voltage protection. In short, TVS diodes are designed to absorb a high voltage spike, limit its duration, and keep its amplitude within safe levels.

Application Field

TVS – diodes are commonly employed in many applications such as industrial control systems, power supplies, medical device applications, embedded systems, automobiles, consumer electronics, etc. Some common applications for TVS installations include telecom networks, aircraft electronics, renewable energy sources, power transformers, and more. TVS – diodes can also be used in the form of transient voltage surge suppressors, or TVs, to help protect electronics from high voltage spikes and provide additional reliability and circuit protection.

Working Principle

TVS – diodes operate by rapidly clamping, or limiting, a high voltage spike, within a certain period of time. This is achieved by a reverse biased p-n junction through which a large current is allowed to flow momentarily. When a large voltage spike occurs, the diode quickly reverses bias, allowing a large, and usually destructive, amount of current to flow through. As this current flows, it is converted to heat energy, which is later dissipated through a heat sink, allowing the circuit to be effectively protected.The typical response time of a TVS – diode is in the range of nanoseconds, which is one billionth of a second, and much faster than any other form of circuit protection. This fast response time is vital in order to protect sensitive electronic components from EMI and EFT.The JAN1N6120A offers exceptional voltage spike absorption (VSA) performance. It features reverse standoff voltage of 6V, working current of 120V, and a working power dissipation of 400W. These parameters make the JAN1N6120A an ideal choice for many applications.

Conclusion

TVS – diodes are a type of transient voltage suppressor designed to protect sensitive electronic components from voltage spikes and power surges. They operate by rapidly clamping a high voltage spike and safely dissipating the excess power. The JAN1N6120A is a common type of TVS – diode with reverse standoff voltage of 6V, working current of 120V, and a working power dissipation of 400W. TVS – diodes are commonly employed in a wide variety of applications, including industrial control systems, power supplies, medical device applications, embedded systems, automobiles, consumer electronics, etc.
