Introduction

Diodes are electronic devices that allow electricity to travel in one direction only, hindering the flow of electricity in the opposite direction. One of the diode categories is the Zener type. The PDZVTR6.8B is an example of a single Zener diode designed by Pan Jit International. This article will aim to explain the application field and working principle of the PDZVTR6.8B.

Application Field

The PDZVTR6.8B single Zener diode is ideal for both DC and AC operation. It is used in a variety of sectors, including the automotive industry, medical equipment, military applications and telecom equipment.It is notable for its low leakage current and is preferred in applications which require low power consumption. Furthermore, its high reverse power capability is beneficial in high energy applications, such as digital circuits.

Working Principle

The PDZVTR6.8B has a Zener breakdown voltage of 6.8 volts, which means it will start to conduct a current and allow electricity to flow when the reverse voltage applied across the diode exceeds this value.A Zener diode allows a large amount of current to flow when it is reverse biased and placed in a certain voltage range, in comparison to the other types of diodes. The current flow in a Zener diode results from the breakdown phenomenon, known as the Zener effect.When the voltage applied across the diode exceeds the breakdown voltage, a population inversion is created. This population inversion is due to electrons and holes flowing from one end to the other of the diode. As the electric field increases, the electron-hole pairs are accelerated, resulting in them gaining enough energy to break the barriers and degrade, producing current flow in the forward direction.

Conclusion

To summarise, the PDZVTR6.8B is a single Zener diode used in a variety of sectors, making it extremely versatile. It is especially beneficial in applications that require low power consumption due to its low leakage current. Its high reverse power capability makes it an ideal choice for high energy applications. Additionally, its working principle is based on the Zener effect, with the electrons and holes flowing from one end to the other producing population inversion when the applied voltage exceeds the breakdown voltage, resulting in current flow in the forward direction.
