The doping level of the zener diode is somewhat higher than the normal pn junction diode. The term zener diode is colloquially applied to several types of breakdown diodes but strictly speaking zener diodes have a breakdown voltage of below 5 volts whilst avalanche diodes are used for breakdown voltages above that value.

In other words the diode which is specially designed for optimising the breakdown region is known as the zener diode.

What is a zener diode definition. A heavily doped semiconductor diode which is designed to operate in reverse direction is known as the zener diode. This article covers the zener diode definition working principle characteristics and applications. A zener diode is a special type of diode that lies at the heart of voltage regulators and circuits generating the reference voltage for a differential amplifier.
Zener diode definition is a silicon semiconductor device used especially as a voltage regulator. Zener diode definition a semiconductor diode across which the reverse voltage remains almost constant over a wide range of currents used especially to regulate voltage. So that it can give a sharp breakdown voltage.
The zener diode is a diode designed to operate in the breakdown region and have a specific negative voltage called the zener voltage. Zener diodes have a highly doped pn junction. Zener diode definition a zener diode is a p n junction semiconductor device designed to operate in the reverse breakdown region.
A special type of pn junction diode that operates in reverse biased mode more specifically in breakdown region is known as zener diode. The usp of a zener diode is that it conducts current in both directions but what is so unique or special about that. The breakdown voltage of a zener diode is carefully set by controlling the doping level during manufacture.
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. At this voltage the diode will go into breakdown. This is a condition allowing current to flow while maintaining a constant voltage across the diode.
A zener diode is a type of diode that allows current to flow not only from its anode to its cathode but also in the reverse direction when the zener voltage is reached.
