TVS - Diodes are a kind of protector that protect crucial equipment from electrical overstress due to voltage spikes caused by lightning. The AK10-030C-12 is an unidirectional TVS-Diode used for automatic overvoltage protection. It has a low capacitance and low leakage current, making it suitable for high speed applications such as HDMI ports and ATX power supplies.

A TVS-Diode is essentially a back to back zener diode configuration. It works by providing a fast clamping action at the breakdown voltage. When an overvoltage spike occurs, the diode turns on and clamps the voltage to a safe level. This prevents any potential damage to the underlying circuitry. The breakdown voltage of the AK10-030C-12 is 12V, so any voltages above this are effectively clamped and prevented from entering the circuit.

The main application of the AK10-030C-12 is on circuit boards that require overvoltage protection. It can be used on computers, camera equipment, automotive electronics, medical equipment and many other electrical products. It is particularly useful for protecting HDMI ports, as these are susceptible to outside interference as well as plugging in incompatible cables. Installing an AK10-030C-12 ensures that any overvoltage spike is quickly clamped and protected from the circuit board.

The AK10-030C-12 has a low capacitance of 2 pF and a low leakage current of 10 uA, making it suitable for high speed applications. This low capacitance helps reduce signal losses, while the low leakage current ensures that the circuitry behind the diode does not become overloaded. Additionally, the AK10-030C-12 also has a low reverse leakage, which prevents reverse charge creepage.

In conclusion, the AK10-030C-12 is an ideal overvoltage protection diode for various applications such as HDMI ports and ATX power supplies. It clamps voltage above 12V, has low capacitance and leakage current, and features a low reverse leakage, making it suitable for high speed applications.
