Zener Diode V-I Characteristics:

 

The VI characteristic of the Zener diode is shown in the figure below. When the diode is connected in forward bias, this diode work like a normal diode. But When a reverse voltage is applied across the diode. initially a small reverse saturation current Io flows across the diode. As the reverse voltage is increased, at a certain value of reverse voltage, the junction will breakdown and drastically a large reverse current flow through the device. This breakdown is called Zener breakdown. The voltage at which this breakdown occurs is called Zener voltage.

1. How should I connect a Zener diode in a circuit?

For voltage regulation, connect the Zener diode in reverse bias (cathode to positive, anode to negative) with a current-limiting resistor.

2. Do these Zener diodes work with AC or DC circuits?

They are primarily designed for DC circuits where voltage regulation is required.

3. Can I use these Zener diodes for voltage reference in microcontrollers?

Yes, they are commonly used as voltage reference sources in ADC circuits and microcontroller applications.

4. Can I use multiple Zener diodes in series or parallel?

Yes, connecting in series increases the total Zener voltage, while parallel connections share the current but should be avoided due to uneven current distribution.

5. Do Zener diodes conduct in forward bias?

Yes, like regular diodes, they conduct in forward bias but are mainly used in reverse bias for voltage regulation.

6. What is the difference between a Zener diode and a Schottky diode?

A Zener diode regulates voltage in reverse bias, while a Schottky diode has a low forward voltage drop and is used for fast switching.

7. Can I use a Zener diode as a voltage booster?

No, Zener diodes only regulate or clamp voltage; they do not increase voltage like boost converters.

8. What is the leakage current of a Zener diode?

In reverse bias, there is a small leakage current (nanoamps to microamps) before reaching breakdown voltage.

9. What is the leakage current of a Zener diode?

In reverse bias, there is a small leakage current (nanoamps to microamps) before reaching breakdown voltage.

10. Can I purchase specific types individually rather than in a pack?

This product is sold as a complete pack, but individual types may be available separately upon bulk request.
