Experiment 1 V-I characteristics of diode charge carriers kept at distance by depletion (acts as a sort of insulation) layer as shown dotted in the above figure. Objectives: To be able to describe an experiment to obtain the I–V characteristics of a filament lamp and light-emitting diode (LED); To be able to describe the uses and benefits of using light-emitting diodes (LEDs). However, there is one major difference. The Complete diode model of a diode consists of the barrier potential, the small forward dynamic resistance and the ideal diode. Chapter 6. When cathode is positive with respect to anode the , the diode said to be reverse biased. 2.0.THEORETICAL BACKGROUND Semiconductor diode theory is at the very center of much of today's electronics industry. Experiment 8 . The resistor approximates the semiconductor resistance under forward bias. I-V characteristics I-V characteristics were introduced in the previous page when introducing Ohm’s law. Select the diode … The horizontal line in the below figure represents the amount of voltage applied across the p-n junction diode whereas the vertical line represents the amount of current flows in the p-n junction diode. You should gather enough data in order to produce a curve like the one shown in Figure 2. The near-linear light output characteristic of an LED is exploited in small length fiber optic analog communication links, such as fiber optic closed-circuit TV. for silicon diode, the cut-in voltage is around 0.7. when diode conducts, there is a forward voltage drop of the order of 0.8 to 1V Reverse Biase V-I characteristic of P-N diode. current-voltage (I-V) characteristics of diodes and the use of diodes in rectifier and limiter circuits. (Houghton Experiment No 1: I/V characteristics PN junction diode Reverse biasing a PN junction When the polarity of the battery is reversed, the cathode is connected to positive end of the battery and anode to negative. The V-I characteristics or voltage-current characteristics of the p-n junction diode is shown in the below figure. Typical i-v characteristic for a semiconductor diode Experimental Procedure Your main task is to determine the i-v characteristic of a 1N4004 silicon diode using a test procedure of your own design. PN Junction Diode : I-V Characteristics üThe barrier increase reduces the majority carrier diffusion to a negligible level üThe p-side electrons and n-side holes can wander into the depletion region and be swept to the other side à reverse I(nàp) üReverse bias situation àan increase of the potential hill üBeing associated with Simulator Procedure (as performed through the Online Labs) Select the characteristics of diode from the drop down list. ii) Junction Voltage vs. Current. Working principle: When voltage is not applied across the diode, depletion region forms as shown in the above figure.
