A TVS diode is a specialized electronic component used for over-voltage protection. Transient Voltage Suppression (TVS) diodes protect important electronic equipment from unexpected, potentially hazardous spikes in electrical power. The distinction between the TVS diode and the Zener diode lies in the breakdown mechanism. Zener diodes rely on the breakdown of the PN-junction to occur while the TVS diode uses an avalanche mechanism. The TVS diode is a surge protection device, one that is temperature and frequency independent whenever the applied voltage remains within specified limits.

One specific TVS diode is the MX15KP85A. The MX15KP85A is a Uni-Directional Silicon Avalanche Diode specifically designed to protect circuits from voltage transients induced by lightning and other transient phenomena. Its maximum ratings are 85V (Stand-off voltage at 25C), 200W peak pulse power (tp=8/20µs), 5 A peak pulse current (tp=8/20µs) and 25A (tp=10/1000µs).

The MX15KP85A’s application field is mainly for protection of Ethernet, RS-485, CAN, HDMI, USB, SATA, and many other data ports. It also provides a wide range of user-selectable peak current ratings which makes it an especially good fit for protecting electronic components in automotive, communications, industrial, security, and consumer electronic applications, among many others. Additionally, this device is RoHS compliant.

When it comes to the working principle of MX15KP85A, the device works in the avalanche breakdown mode, where the voltage increases in steps by an increasing current breakdown process until it ultimately reaches the clamping voltage. The breakdown voltage of the diode is dependent on the specific design of the device, which is usually done at the manufacturer. In the case of the MX15KP85A, it is rated for a stand-off voltage of 85V and a peak pulse current rating of 5A.

The device also has a fast response to transient voltages, meaning that it can quickly clamp and divert voltages within microseconds, thus preventing any transient induced damages from occurring. Upon exposure to an overvoltage, the protection diode doesn’t just clamp the voltage at its peak value, instead, it follows the overvoltage waveform until it returns back within normal limits.

In conclusion, TVS devices, such as the MX15KP85A, are invaluable tools in protecting important electronic components from voltage transients. They are easily integrated into existing circuits and provide fast response times that defend against potentially dangerous spikes in power. They are a highly effective, reliable, and cost-effective form of overvoltage protection.
