Diodes form the foundation of modern electronic circuits. They are used in a variety of applications and come in numerous varieties with distinct characteristics. The VDZT2R2.4B is a type of diode known as a Zener diode and is used because of its specific characteristics in certain applications.

This article seeks to discuss the application field and the working principle of the VDZT2R2.4B, with an aim to categorizing it as one of the diodes – Zener – Single.

Application Field

The Zener diode VDZT2R2.4B is used for voltage regulation purposes. This type of diode can, with the appropriate biasing parameters and a few additional components, be made to provide a regulated, constant output voltage.

In such an application, a voltage divider network is used to generate a biasing voltage which is applied to the zener diode. This biasing voltage is set at a value above the zener breakdown voltage (Vz). The load is connected to the output of the voltage regulator which is the cathode side of the zener.

The regulation works in the following way: As the input voltage increases, the voltage regulator will draw more current and reduce the terminal voltage at the output to maintain the voltage set by the voltage divider and biasing voltage across the zener diode. This limits the output voltage to a set value and protects the load from too much voltage.

Working Principle

The working principle of the VDZT2R2.4B Zener diode is divided into two stages. In the first stage, the diode operates as a regular diode, allowing the current to pass in only one direction, from anode to cathode. In this stage, the diode acts as a simple switch, allowing or blocking the current with the help of the junction potential.

Then, in the second stage, the biasing voltage increases until it reaches the Zener breakdown voltage (Vz). In this stage, the diode turns into a reverse biased diode and the re-generation of the electrons, which was initially prevented by the junction potential, starts to happen. This phenomenon enables the diode to prevent the terminal voltage at the output to remain constant and drop any extra voltage over the Zener breakdown voltage.

Conclusion

The VDZT2R2.4B is a type of zener diode which is used for voltage regulation in electronic circuits. The working principle of this diode involves two stages: a first stage in which the diode operates as a regular diode, and a second stage in which the diode acts as a reverse-biased diode and the re-generation of the electrons starts to occur.

Therefore, the VDZT2R2.4B can be categorized as one of the diodes – Zener – Single.
