EDZVFHT2R5.6B application field and working principle

EDZVFHT2R5.6B is a Zener diode that is commonly used for voltage regulation, surge suppression, and point of load regulation in a variety of applications such as power supplies, data communications, and automotive electronics. It is a single diode-based component with a reverse breakdown voltage of 2.5 V and a power dissipation of 0.6 W.

A Zener diode is a type of semiconductor diode specifically designed to conduct in reverse bias conditions. In normal diode operation, if the applied voltage exceeds the breakdown voltage, the diode will enter a high-current state of avalanche breakdown. Zener diodes, in contrast, are designed to sustain reverse breakdown. As the voltage increases, the diode begins to operate in reverse bias and the current remains relatively constant due to the potential barrier formed by the valence-shell electrons.

The breakdown voltage of the EDZVFHT2R5.6B is determined by the doping concentration of its semiconductor material, which is a measure of the number of impurities added per unit volume. By controlling the doping concentration, the Zener diode manufacturers are able to achieve a precise breakdown voltage. The breakdown voltage is typically documented with a tolerance of +/- 5%; however, if the application requires a higher degree of accuracy, the manufacturer may provide a larger tolerance.

The working principle of a Zener diode allows it to be used in voltage regulation circuits. In such a circuit, a steady current source is connected along with an adjustable load and the Zener diode. When the load is increased, the voltage across the Zener diode increases, which causes it to enter a reverse breakdown state. When the load is decreased, the voltage across the diode begins to decrease, which causes it to enter a low-current forward bias state. The result is that the voltage across the diode remains relatively constant despite changes in the load. This phenomenon is known as “Zener regulation” and is used in many applications in order to provide stability in the output voltage.

The EDZVFHT2R5.6B Zener diode can be used for a variety of functions including voltage regulation, point-of-load regulation, surge suppression, and circuit protection. These diodes are particularly useful in high-voltage applications since their breakdown voltage can be selected precisely. They are also useful in applications requiring a long operating life as they can handle high temperatures and high current values without significant wear or degradation. However, it is important to be mindful of their power rating as they are only rated for 0.6 W of power dissipation.
