☑ Explain Zener Diode As Voltage Regulator

The zener diode compensates for the variation in load current. In breakdown the voltage across the zener diode is close to constant over a wide range of currents thus making it useful as a shunt voltage regulator.

Zener diode as a voltage regulator zener diode is a silicon semiconductor with a p n junction that is specifically designed to work in the reverse biased condition.

Explain zener diode as voltage regulator. The stabilised output voltage is always selected to be the same as the breakdown voltage v z of the diode. The zener voltage regulator consists of a current limiting resistor r s connected in series with the input voltage v s with the zener diode connected in parallel with the load r l in this reverse biased condition. A simplified typical zener regulating circuit is shown below.

After the fact that it exhibits the zener effect that is a specific type of voltage break down so the diode is called zener regulator. When forward biased it behaves like a normal signal diode but when the reverse voltage is applied to it the voltage remains constant for a wide range of currents. A regular diode will not work effectively as a zener diodeand vice versa.

The diodes used as voltage regulators are called zener diodes. Zener diode is a special purpose diode that is used in reverse biased to regulate voltage across it. A zener diode is manufactured for lower and exact reverse break down voltage.

The purpose of a voltage regulator is to maintain a constant voltage across a load regardless of variations in the applied input voltage and variations in the load current. Zener diode example no1.
