Which of the following diode is used as regulator?

Zener diode
Notes: Zener diode is a special purpose semiconductor diode, named after its inventor C. Zener. It is designed to operate under reverse bias in the breakdown region and used as a voltage regulator.

What is Zener diode used as?

A Zener diode is also known as a breakdown diode and it is mainly used as a voltage regulator. A Zener diode can be used as a voltage regulator or voltage stabilizer to provide a constant voltage from a source whose voltage may fluctuate over a wide range.

What characteristics of the Zener diode make it suitable to be employed as a regulator in the power supply?

Additionally, the voltage drop across the diode remains constant over a wide range of voltages, a feature that makes Zener diodes suitable for use in voltage regulation. The Zener diode operates just like the normal diode when in the forward-bias mode, and has a turn-on voltage of between 0.3 and 0.7 V.

In which bias is Zener diode used?

reverse biased
Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. When connected in parallel with a variable voltage source so that it is reverse biased, a Zener diode conducts when the voltage reaches the diode’s reverse breakdown voltage.

How does Zener diode differ from PN junction diode?

The main difference between the PN junction diode and the Zener diode is that the PN junction diode allows the flow of electron in one direction only, whereas the Zener diode allows the flow of electron in both directions.

How does Zener diode different from PN junction diode?

The major difference between PN junction and the Zener diode is that the PN junction diode allows current to pass only in the forward direction, whereas the Zener diode allows the current to flow both in the forward and the reversed direction.

When does a Zener diode act as a normal diode?

Zener diodes act like normal diodes when forward-biased. However, they are designed to allow current to flow in reverse once the reverse voltage equals its rated Zener Voltage. Unlike ordinary rectifier diodes, which are never intended to be operated at or near breakdown, a Zener diode is designed to operate in the breakdown region.

What is the purpose of a Zener diode?

Zener diodes are widely used in electronic equipment of all kinds and are one of the basic building blocks of electronic circuits. They are used to generate low power stabilized supply rails from a higher voltage and to provide reference voltages for circuits, especially stabilized power supplies.

How is a Zener diode different from a regular diode?

Difference Between Diode and Zener Diode Diode can conduct current only in one direction, whereas zener diode allows the conduction in both directions. A normal diode will be permanently damaged for a large reverse current, but a zener diode will not. Amount of doping for P and N semiconductor layers are different in the two devices.

What type of diode is used in a voltage regulator?

Zener diodes found its use in several applications. They are widely used as voltage reference diodes in electronics circuits that allow simple and stable reference voltage regulator circuits to be prepared, as well as they are cheap and easy to manufacture.
