In the reverse biased mode zener diode has large breakdown voltage and though the current increases the voltage remains constant. In the forward biased mode the zener diode operates as a p-n diode. To study the voltage regulation in Zener diode regulation circuit. The electric field may become large enough that covalent bonds are broken and electron-hole pairs are created. While doing the experiment do not exceed the ratings of the zener diode. Thus it acts as a voltage regulator. 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 . The forward characteristics of a diode is non linear. P-N Junction Diode Characteristics 3. To construct a Zener voltage regulator and experimentally determine the range over which the Zener maintains a constant output voltage. Result: a. The fixed voltage property of Zener diodes makes them extremely handy as quick voltage references. The zener diode characteristics … The V-I characteristics of a diode can be forward or reverse. Experiment no. EXPERIMENT: DIODE & ZENER DIODE Objective:- To study the forward and reverse bias characteristics of diode and zener diode. Here the Zener diode acts like an ordinary diode.When a forward voltage is applied, current flows through it. Objectives: To study the characteristics of Zener diode. Zener doide is a special diode with increased amounts of doping. 1. A p-n junction diode normally does not conduct when reverse biased. 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. 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. But due to higher doping concentration, higher current flows through the Zener diode.In the third quadrant, the magic happens. David started the tutorial comparing between zener and regular diode. The P type has excess 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 … Theory. (ii) REGULATION CHARACTERISTICS: THEORY: A zener diode is heavily doped p-n junction diode, specially made to operate in the break down region. 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. Zener voltage references. List of Experiments Minimum of Ten Experiments need to be conducted 1. Rectifiers (without and with filter) i) Half-wave Rectifier ii) Full-wave Rectifier 5. Study of CRO Operation and its Applications. Zener Diode Characteristics i) V-I Characteristics ii) Zener Diode act as a Voltage Regulator 4. current increases at a rapid rate. 2. With 2 V across a 400 ohm resistor, the current through that resistor (and the diode, in series) is 5 mA. Brief Theory: When a reverse-bias voltage is applied to a pn junction, the electric field in the space-charge region is increases. Theory:-A Semiconductor diode is prepared by joining P and N sections of a semi conducting material like germanium or silicon. 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 circuit diagram to plot the VI characteristics of a zener diode is shown. In the circuit above, there is 10 V across the Zener diode, and 2 V across the resistor. This may lead to damage the diode. Apparatus:-Experimental kit and patch cords. Here V z is the Zener breakdown voltage. : 5 Lab. 2.
