A Zener diode is a type of pn junction diode. Zener diodes are used in the breakdown region (yield region) by applying a voltage in the opposite direction to normal pn junction diodes.

Unfortunately, when normal rectifying diodes “break down,” they usually do so destructively. However, it is possible to build a special type of diode that can handle breakdown without failing completely. This type of diode is called aZener diode, and its symbol is shown in the figure(b) ...
Zener Diode Circuit Zener Diodeis nothing but a singlediodeconnected in a reverse bias, we have already stated that. A diode connected in reverse bias position in a circuit is shown below, The circuit symbol of aZener diodeis also shown below. ...
TheZener diodeis a special diode, that enables the current to flow not only from the positive terminal (anode) to the negative terminal (cathode) but also in the opposite direction. The doping of the Zener diode is more than the conventional diode, so its depletion part has less area. ...
Zener Diode A very useful type of diode, it offers a stable reference voltage. They work in reverse bias and break down when a certain voltage is hit, but when the current flowing through the resistor is limited, a stable voltage is produced. Zener diodes are mainly used in power supplies...
The Diode Circuit Symbol A diode is a semiconductor that has only two terminals. Terminals are the leads on each end of the diode that get soldered to your circuit board (or inserted into a breadboard when prototyping). Unlike resistors, diodes are polarized. It matters which direction they ...
Diode schematic electrical symbol In Other Words, a Diode is a Valve! As previously mentioned, if you were to think of an image that exemplifies the effects of a diode, you might think of it as a “valve” for electrical current. If you think of electrical current as flowing water, the...
Step 1: Definition of Zener DiodeA Zener diode is a type of semiconductor diode that allows current to flow in the reverse direction when the voltage exceeds a certain value known as the Zener breakdown voltage. Unlike regular diodes, Zener diodes are designed to operate in the breakdown region...
When a diode allows current flow, it is forward-biased. When a diode is reverse-biased, it acts as an insulator and does not permit current to flow. Strange but true: The diode symbol's arrow points against the direction of electron flow. The reason is that engineers conceived the symbol...
