To study the voltage regulation in Zener diode regulation circuit. In the reverse biased mode zener diode has large breakdown voltage and though the current increases the voltage remains constant. Theory. The fixed voltage property of Zener diodes makes them extremely handy as quick voltage references. Thus it acts as a voltage regulator. 2. The zener diode characteristics … David started the tutorial comparing between zener and regular diode. To construct a Zener voltage regulator and experimentally determine the range over which the Zener maintains a constant output voltage. 1. Objectives: To study the characteristics of Zener diode. Here the Zener diode acts like an ordinary diode.When a forward voltage is applied, current flows through it. Study of CRO Operation and its Applications. The graph showing the forward bias voltage and forward current is known as the forward characteristics, and that showing the reverse bias voltage and reverse current is known as the reverse characteristics. The electric field may become large enough that covalent bonds are broken and electron-hole pairs are created. A p-n junction diode normally does not conduct when reverse biased. A graph of current through vs the voltage across the device is called the characteristic of Zener diode.The first quadrant is the forward biased region. The forward characteristics of a diode is non linear. List of Experiments Minimum of Ten Experiments need to be conducted 1. Zener doide is a special diode with increased amounts of doping. The circuit diagram to plot the VI characteristics of a zener diode is shown. 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 . This may lead to damage the diode. current increases at a rapid rate. The P type has excess In the circuit above, there is 10 V across the Zener diode, and 2 V across the resistor. EXPERIMENT: DIODE & ZENER DIODE Objective:- To study the forward and reverse bias characteristics of diode and zener diode. We are going to learn about an experiment to find out the Zener breakdown voltage and draw the characteristics of Zener diode.Why should we do this experiment? 2. Theory:-A Semiconductor diode is prepared by joining P and N sections of a semi conducting material like germanium or silicon. Here V z is the Zener breakdown voltage. Rectifiers (without and with filter) i) Half-wave Rectifier ii) Full-wave Rectifier 5. While doing the experiment do not exceed the ratings of the zener diode. Zener voltage references. Zener Diode Characteristics i) V-I Characteristics ii) Zener Diode act as a Voltage Regulator 4. In the forward biased mode the zener diode operates as a p-n diode. Apparatus:-Experimental kit and patch cords. But due to higher doping concentration, higher current flows through the Zener diode.In the third quadrant, the magic happens. For correct voltage regulation, we need to find out precisely what voltage should be across the Zener diode.Zener breakdown voltage should be approximately close to the desired … Result: a. 2. Supervisor: Munther N. Thiyab Zener diode characteristics 1 Experiment #5 Object To study and measure the effects of forward and reverse bias on the Zener diode current. The V-I characteristics of a diode can be forward or reverse. : 5 Lab. With 2 V across a 400 ohm resistor, the current through that resistor (and the diode, in series) is 5 mA. P-N Junction Diode Characteristics 3. (ii) REGULATION CHARACTERISTICS: THEORY: A zener diode is heavily doped p-n junction diode, specially made to operate in the break down region.
