TVS - Diodes

TVS diodes, or transient voltage suppressor diodes, are an invaluable component of any electronic system, protecting vulnerable circuits from large voltage spikes and transients. JANTXV1N6123A is a great example of these critical electronic components.

JANTXV1N6123A Application Field

JANTXV1N6123A TVS diode is a special voltage protection part, designed for the protection of sensitive electronic components, like circuit boards, from a high-energy transient surge. It provides an extra layer of protection between the device and the external surge, safely dissipating the energy instantaneously reaching the device. JANTXV1N6123A diode can be used to guard against threats such as overvoltage conditions, overrating conditions, excessive current ratings, as well as other common causes of device damage.

JANTXV1N6123A Working Principle

The working principle of the JANTXV1N6123A TVS diode is known as “multi-layer avalanche clamping”. It is based on a special type of reverse-biased zener diode designed for integrated circuit protection against transients and large overvoltages. The JANTXV1N6123A diode consists of a series of resistors connected in series with a zener diode at its base, tied together to form a combined avalanche diode that is triggered by a transient surge and which prevents high-energy transients from passing through the circuit.

Essentially, during normal operation the zener diode is reverse-biased, so current does not flow through the zener diode and its resistors. However, when the applied voltage exceeds the reverse-biased voltage of the zener diode, a large current surge is generated and quickly dissipated before it reaches the sensitive components.

This ensures that the energy of the surge is quickly distributed away from the circuit and is not held long enough to cause any permanent damage. The diode is designed to handle even the largest spikes without suffering any permanent damage itself, thus keeping the circuit intact.

Conclusion

In a modern electronics age, transient voltage suppressors like the JANTXV1N6123A are essential components for protecting sensitive electrical components from transients. By utilizing the multi-layered avalanche clamping design, the JANTXV1N6123A is able to clamp voltage and current spikes, thus protecting connected components.
