TVS - Diodes play a vital role in the field of circuit protection and electricity conduction. The 15KPA85-B is a perfect example of this technology being implemented. This high voltage surge arrester diode works by diverting the surge current away from the main circuits, thus protecting sensitive internal components from damage due to high voltage. This article will discuss the application field and working principle of the 15KPA85-B.

The 15KPA85-B is often used in power systems and railway applications. This diode is capable of handling high voltage surge currents up to 5000V. This makes it ideal for protecting transformers, distribution networks and other equipment. It can also be used in industrial control systems, communications networks and other low-voltage applications. The diode is also available in different packages, depending on the application.

The working principle of the 15KPA85-B is quite simple. When it is exposed to a high voltage, the diode acts like a switch and redirects the current to the external circuit. This process of redirection occurs in the following manner: the voltage is applied to the anode, which causes the PN junction to be biased. This bias causes the electrons to flow in the external circuit and the current is diverted away from the main circuit.

As the voltage rises, the diode reaches a saturation point where the electrons cannot flow any further. This causes the voltage to be diverted to the external circuit and prevents the main circuit from being damaged due to the high voltage. The current will then follow the path of least resistance, thus protecting the main circuit from damage.

The 15KPA85-B diode is also designed with a, voltage-dependent, non-linear resistive element that provides a resistance path for the surge current. This element also helps reduce the surge current in the main circuit. The diode is also designed with a temperature-dependent element that helps keep the voltage constant, regardless of the external temperature changes.

In conclusion, the 15KPA85-B diode is an excellent choice for protecting sensitive components from high voltage. It can handle high voltage surge up to 5000V and is designed with multiple protective elements. This diode is suitable for use in numerous power system and railway applications. Its working principle involves redirection of the current to an external circuit, which prevents the main circuit from being damaged due to high voltage.
