TVS - Diodes are commonly used in a variety of applications, particularly those that require protection from transient voltage spikes or electrical surges. Of these devices, the 3KP8.5-B is a popular choice, providing impressive protection from electrical overstress caused by surges in power, radio-frequency (RF) interference, lightning strikes, and other events. This article will discuss the 3KP8.5-B\'s application field and working principle.

3KP8.5-B Application Field

The 3KP8.5-B is typically used as a surge protection device in AC power systems and can easily be integrated into any equipment’s circuits. 3KP8.5-B is a bidirectional device, meaning it can work in reverse directions in a single symmetrical transient pulse waveform. Its bidirectional capability also enables it to absorb transient spikes in both the positive and negative directions, providing maximum protection against both DC and AC power components.

In electrical systems, the 3KP8.5-B also has an impressive ability to limit surge currents, suppressing them to a safe level. It can protect systems in a variety of industries, including medical electronics, industrial automation, communication, automotive, and fire safety systems. Furthermore, the 3KP8.5-B is also designed to ensure immunization from the high-voltage surges caused by lightning strikes.

3KP8.5-B Working Principle

The 3KP8.5-B is constructed from a zinc oxide (ZnO) conductor path arranged in the form of a transient voltage suppressor (TVS). In order to prevent overvoltage surges, the ZnO conductor path absorbs the extra energy and dissipates it without allowing it to reach the system. The ZnO conductor path of the 3KP8.5-B is designed to respond to voltage surges faster than other silicon-based components such as MOSFET or bipolar transistors.

The 3KP8.5-B integrates two PN junctions with heavy doping on both sides. In the presence of a surge, current from the external oscilloscope will be diverted to the junction’s positive side while the current from the external source will be diverted to the negative side. This efficiency also helps prevent the secondary breakdown of the component.

TVS diodes, such as the 3KP8.5-B, are important components in any system that requires surge protection. They provide impressive protection from both DC and AC sources, helping prevent system damage caused by power-side transients. Furthermore, the 3KP8.5-B is suitable for a wide range of applications thanks to its fast response time and bidirectionality.
