What is the application of Zener diode Mcq?

What is the application of Zener diode Mcq?

A Zener diode is used as a voltage regulator in reverse biased mode. The breakdown voltage in the Zener diode when connected in the reverse-biased is called Zener voltage. This Zener voltage is steady and constant and it has huge applications in circuits, most importantly, voltage regulation.

What is the main application of diode?

The most common and important application of a diode is the rectification of AC power to DC power. Using diodes, we can construct different types of rectifier circuits. The basic types of these rectifier circuits are half wave, full wave center tapped and full bridge rectifiers.

Which of the following purposes is a Zener diode?

Because of this property, Zener diodes are widely used as constant-voltage devices. A Zener diode permits Zener current, Iz, to flow when the voltage is above the specified Zener voltage. Thus, a Zener diode can be used for voltage detection by sensing Zener current with some other device.

What are the types of diode applications?

Diode Types | Types of diodes with their applications and functions

  • Zener diode. When reverse biase voltage is increased to ordinary junction diodes until depletion region breaks down, the diode suffers permanent damage.
  • Point-contact diode.
  • Varactor diode.
  • Gunn diode.
  • Tunnel diode.
  • PIN diode.
  • Impatt diode.
  • Trapatt diode.

Why are zener diodes used as voltage regulator?

Applications for Zener Diodes The Zener diode is often in use as a voltage regulator, primarily because the voltage drop across the diode is constant. This is not only due to its ability to produce a stable voltage output but also because it does so with low ripple while under varying load current conditions.

Can Zener be used as a rectifier?

Zener diodes are never worked for rectification purposes. Complete step-by-step solution: We do not favour using a Zener Diode in a rectifier circuit because a large maximum peak inverse voltage is needed for a rectifier circuit. Unlike the standard p-n junction diode, a Zener diode has a below peak inverse voltage.

Why Zener diode is used in reverse bias condition?

Zener diode is a heavily doped diode. It acts as a normal diode in forwarding bias. When the Zener diode is reverse biased the junction potential increases. Therefore the Zener diode turns into a perfect conductor and will drain the current through it.

Why Zener diodes are provided in DC supply?

5. Why zener diodes are provided in dc supply? Explanation: Zener diodes in dc power supplies are used for providing a reference voltage used for comparison. Explanation: Stability of zener diodes used is an important factor in determining the stability of output voltage in dc power supply.

How many types of Zener diode are there?

two types
The principle behind the operation of a Zener diode is determined by the cause of the diode’s breakdown in the reverse bias condition. There are typically two types – Zener and avalanche.
