Zener Diode Schaltung. Zener diode is used as a shunt voltage regulator for regulating voltage across small loads. Zener diode is connected parallel to the load to make it reverse bias and once the zener diode exceeds knee voltage the voltage across the load will become constant.
The breakdown voltage of zener diodes will be constant for a wide range of current. It always works in zener breakdown voltage. Zener diode as voltage regulator.
If you use a zener diode instead of a resistor below the zener voltage the led will not illuminate.
Zener diode is connected parallel to the load to make it reverse bias and once the zener diode exceeds knee voltage the voltage across the load will become constant. 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. It allows the current to flow as like a normal pn junction diode when it is forward biased and block the reverse flow of current during the reverse bias up to the breakdown voltage. Zener diode is used as a shunt voltage regulator for regulating voltage across small loads.
