What Is The Zener Diode Used For

Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. It is so helpful device in electronics.

The clipping circuit limits or clips off parts of one or both of the half cycles of an ac waveform to shape the waveform or provide protection.

What is the zener diode used for. When connected in parallel with a variable voltage source so that it is reverse biased a zener diode conducts when the voltage reaches the diodes reverse breakdown voltage. The circuit diagram showing the zener diode being used as a voltage regulator is shown below. Butdo you understand good enough.

We often use a zener diode in a lot of the electronic circuits. For example if you pass a reverse 5v through a 3v zener diode and measure the voltage across the zener diode that voltage will be 3v. Today we will learn zener diode principle working and example applications usage.

That is why we use a zener diode mainly for controlling voltage in different circuits. For instance power supplies voltage detectors etc. Zener diode clipping circuits zener diodes are used to modify or shape ac waveform clipping circuits.

Zener diode circuit zener diode is nothing but a single diode connected in a reverse bias we have already stated that. Uses of zener diodes since the voltage dropped across a zener diode is a known and fixed value zener diodes are typically used to regulate the voltage in electric circuits. A resistor r1 is connected in series with the zener diode to limit the amount of current flowing through the diode and the input voltage vin which must be greater than the zener voltage is connected across as shown in the image and the output voltage vout is taken across the zener diode with vout vz zener voltage.
