Zener Diode Schaltung. A zener diode is among the specifically developed diodes that mainly functions in reverse biased circumstances. 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.

If you use a zener diode instead of a resistor below the zener voltage the led will not illuminate. A zener diode is among the specifically developed diodes that mainly functions in reverse biased circumstances. Above the zener voltage the zener diode will conduct and the led will illuminate for a brief moment as there is nothing limiting current flow so either the zener or led whichever is first will be damaged due to overcurrent.
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.
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. These are a lot more intensely doped compared to normal diodes because. Some zener diodes have a sharp highly doped p n junction with a low zener voltage in which case the reverse conduction occurs due to electron quantum tunnelling in the short space between p and n regions. It always works in zener breakdown voltage.
