The Zener diode is a special type of diode that is designed to work in reverse bias and in the so-called Zener region of the diode characteristic curve. This article covers the Zener diode definition, working principle, characteristics, and applications.

The positive current enters the anode of Zener Diode (ZD1) via Resistor (R1). The operation of a Zener diode is like a general diode. Zener diode is similar to conventional PN Junction diode except that it is properly doped in order to achieve sharp breakdown voltage. There are two types of mechanism by which breakdown can occur at reverse PN junction that are avalanche breakdown and Zener breakdown.

Overview: Zener diode is a special type of Diode specifically designed to operate in reverse biased mode. Zener diodes are available in the range from 3V to 200 Zener Diode Clipping Circuits: Zener diodes are in use to modify or shape the AC waveform clipping circuits. The clipping circuit limits or some parts of one or both of the half cycles of an AC waveform. It is needed to shape the waveform or provide protection. Therefore the Zener diode is useful for converting the sine wave into the square wave.

The Zener Diode is used in its “reverse bias” or reverse breakdown mode, i.e. the diodes anode connects to the negative supply. From the I-V characteristics curve above, we can see that the zener diode has a region in its reverse bias characteristics of almost a constant negative voltage regardless of the value of the current flowing through the diode.

Dies wollen wir einmal nachmessen. Unser Messgerät beweist uns, dass dieser Wert ziemlich genau eingehalten wird. 2019-12-17 · Zener diodes are immensely helpful for voltage regulation. The Characteristics of a Zener Diode.
