Zener Diode As Voltage Regulator Explanation. This is how zener diode is used as voltage regulator. The depletion layer at the reverse biased pn junction acts like an insulator1.
Zener Diode as a Voltage Regulator Working Principles from byjus.com
It only requires a single resistor for configuring a zener diode based voltage regulator stage, and can be quickly added to any circuit for the intended. Zener diodes are easy to configure and can be used to get a reasonably accurate stabilized output under all circumstances. The zener diode or voltage reference diode is an electronic component that provides a stable and defined voltage.
The Figure Below Shows The Circuit Arrangement Of The Zener Diode As A Regulator.
Zener diode is used as a shunt voltage regulator for regulating voltage across small loads. The fixed voltage property of zener diodes makes them extremely handy as quick voltage references. The major application of a zener diode in the electronic circuit is as a voltage regulator.
1) Zener Diode As A Voltage Regulator:
Voltage regulators] procedures and explanations 1 zener diode shunt voltage regulator when an ideal diode is reverse biased, it conducts no current. The voltage remains constant even with a large change in current. The breakdown voltage of zener diodes will be constant for a wide range of current.
A Zener Diode Is A Special Type Of Diode Designed To Reliably Allow Current To Flow Backwards When A Certain Set Reverse Voltage, Known As The Zener Voltage, Is Reached.
Zener diode as voltage regulator. This constant voltage drop across the zener diode produced by reverse breakdown is represented by a dc voltage symbol. In the circuit above, there is 10 v across the zener diode, and 2 v across the resistor.
Voltage Regulator Or Stabilizer To Provide A Constant Voltage From A Source Whose Voltage Varies Over A Wide Range.
Zener diode as a voltage regulator: This ability of a zener diode to control itself can be used to regulate or stabilize the voltage source against supply or load variation. Zener diodes are very handy where low current, constant voltage regulation is required.
As Shown In The Graph To Understand The Working Of Zener Diode Let’s First Understand
Due to this property zener diode being operated in the breakdown region can be used as a voltage regulator. As a result zener diode circuits are often used in power supplies when regulated outputs are needed. With 2 v across a 400 ohm resistor, the current through that resistor (and the diode, in series) is 5 ma.
