AIM To plot the reverse characteristics of zener diode and to find the breakdown voltage COMPONENTS AND EQUIPMENTS NEEDED 1. 6.2 V zener diode 2. Resistors 3. Variable dc power supply 4. Voltmeter 5. Ammeter CIRCUIT DIAGRAM THEORY Zener diode is a P-N junction diode specially designed to operate in the reverse biased mode.

These types of diodes are commonly known as Zener Diodes and are discussed in a later tutorial. Forward Biased PN Junction Diode. When a diode is connected in a Forward Bias condition, a negative voltage is applied to the N-type material and a positive voltage is applied to the P-type material. If this external voltage becomes greater than the ...

08/10/2018 · We use semiconductor materials (Si, Ge) to form variety of electronic devices. The most basic device is diode.Diode is a two terminal PN junction device. PN junction is formed by bringing a P type material in contact with N type material. When a P-type material is brought in contact with N- type material electrons and holes start recombining near the junction.

Zener diodes are normal PN junction diodes operating in a reverse biased condition. Working of the Zener diode is similar to a PN junction diode in forward biased condition, but the uniqueness lies in the fact that it can also conduct when it is connected in reverse bias above its threshold / breakdown voltage.

26/01/2017 · The PN junction region of a Junction Diode has the following important characteristics: Semiconductors contain two types of mobile charge carriers, Holes and Electrons. The holes are positively ...

Zener Diode V-I Characteristics. Zener diode is nothing but a single diode connected in a reverse bias mode and Zener diode can be connected in reverse bias positive in a circuit as shown as picture.we can connect it for different applications.

Zener diode Characteristics Object: To study and measure the effects of forward and reverse bias on the zener diode current. To construct a zener voltage regulator and experimentally determine the range over which the zener maintains a constant output voltage. Theory: Diodes which are designed with adequate power dissipation capabilities to operate

Theory. The circuit diagram to plot the VI characteristics of a zener diode is shown. Zener doide is a special diode with increased amounts of doping. This is to compensate for the damage that occurs in the case of a pn junction diode when the reverse bias exceeds the breakdown voltage and thereby . current increases at a rapid rate.

Zener diode is a P-N junction diode specially designed to operate in the reverse biased mode. It is acting as normal diode while forward biasing. It has a particular voltage known as break down voltage, at which the diode break downs while reverse biased. In the case of normal diodes the diode damages at the break down voltage.

The voltage across the diode remains reasonably constant at this time. This constant-voltage characteristic leads to a number of applications of diode under reverse bias condition. The processes which are responsible for current conduction in a reverse-biased diode are called as Avalanche breakdown and Zener breakdown. Diode Specifications
