TVS - Diodes

TVS (transient voltage surge suppression) diodes are electronic protectors designed to suppress voltage transients caused by incompatibility of electronic load on the power supply. The ATV06B131JB-HF is a member of this type of surge suppressor family, with its peak pulse current of 600A, and its pulse width of 8.3ms.

Application Field

ATV06B131JB-HF has a voltage rating of 13V and a working voltage of 11V. This makes it an ideal choice for applications where the used equipment protection level only requires 11V. It can be used in both AC and DC circuits as a safeguard against voltage transients. The applications include consumer electronics, avionics, automotive electronics, industrial and medical equipment, and telecommunications.

Working Principle

As soon as an over-voltage surge occurs, the diode conducts current, reducing the level of the surge, thus protecting the equipment from damage. A normal Zener diode conducts in the forward direction, while a TVS diode conducts in both forward and reverse directions. The ATV06B131JB-HF is a PNP type diode, which means that the diode can conduct for both positive and negative transients. The reverse conduction capability makes it more effective in dealing with voltage transients, making it a better choice for electronic equipment protection.

The ATV06B131JB-HF working principle primarily involves controlling the voltage surge through the diode’s effective reverse conduction capability. It works by dissipating the surge energy to earth while limiting the voltage rise across the equipment. This is done through the "clamping" of the voltage wave. The diode used in this surge suppressor has an effective capacitance that reduces the rate of voltage rise and helps prevent equipment breakdown.

The ATV06B131JB-HF is a useful addition to any board-level circuit protection scheme. It offers a great degree of protection to sensitive electronic components, and it has a good price to performance ratio that makes it an attractive option for many applications.
