To calculate static and dynamic resistances of the Zener diode in both forward and reverse biased conditions (before, after break down voltages). Figure 2. C. Half Wave Rectifier Build the rectifier circuit shown in Figure 4. Plot the reverse characteristic curve by taking reverse voltage along –ve X-axis and reverse current along –ve Y-axis. 10-1 2 Understand Zener Diode Datasheet Specifications. When forward biased voltage is applied to the zener diode, it works like a normal diode. With these, the group was able to observe how a Zener Diode acts like a rectifier diode when it is forward bias and a voltage regulator when it is in reverse bias. • To measure the important parameters of Zener Voltage Regulator. This is considered as the basic application of Zener diode. To Study the working of a diode as half w ave rectifier with and without filter. The critical parameter of this type of diodes is the Zener breakdown voltage. To Study the V-I characteristics of Forwa rd Biased PN junction diode.
