Zener Diode Experiment
The Zener diode mainly operates in reverse biased condition. We use Zener diodes for voltage regulation and voltage stabilisation. They provide a low-cost and no frill method for voltage regulation. The critical parameter of this type of diodes is the Zener breakdown voltage. The Zener breakdown voltage is the minimum reverse biased voltage below which the diode blocks the reverse current through it and above which it causes a significant amount of reverse bias current to flow through it. Once the reverse voltage reaches the Zener breakdown voltage, the voltage across the device remains constant at that level. Hence we can use Zener diode for voltage regulation. The graph of voltage vs current of a diode is called its characteristic. Below you can see the characteristic.
We need the following equipment:

Zener Diode. A Zener Diode is a special kind of diode which permits current to flow in the forward direction as normal, but will also allow it to flow in the reverse direction when the voltage is above the breakdown voltage or 'zener' voltage.u000b Zener diodes are designed so that their breakdown voltage is much lower - for example just 2. ...

Theory Overview. When forward biased, the Zener diode behaves similarly to an ordinary switching diode, that is, it incurs a. 0.7 volt drop for silicon devices. Unlike a switching diode, the Zener is normally placed in reverse bias. If the circuit potential is high enough, the Zener will exhibit a fixed voltage drop.
