Summary On Module 1 P N Junction Diode Applications Pdf P N Unit1 theory ece free download as pdf file (.pdf), text file (.txt) or read online for free. this document provides an overview of semiconductor diodes and their applications. A pn junction diode is said to be reverse biased when the positive terminal of a cell or battery is connected to the n side of the junction and the negative terminal to the p side.
P N Junction Diode Definition Formation Characteristics 52 Off Under reverse bias filled states on the p side become increasingly aligned with empty states on the n side and electrons now tunnel through the pn junction barrier in reverse direction – this is the zener effect that also occurs in zener diodes. These devices differ from other diodes in that their rectifying junction is formed by a special metal semiconductor junction, instead of a standard pn junction. N channel devices have greater conductivity than p channel types, since electrons have higher mobility than do holes; thus n channel jfets are approximately twice as efficient conductors compared to their p channel counterparts. This chapter introduces the construction, working, characteristics and applications of p n junction diode and other special diodes like zener diode, photodiode, led.

This relates the majority minority carrier concentration on either side of the junction. which becomes more useful next lecture(s) when we apply an external voltage. The notes available on edurev are crafted specifically for gate ece preparation, covering all eight core subjects: network theory, signals and systems, digital circuits, control systems, electronic devices, analog circuits, communication systems, and electromagnetics. The critical value of the voltage, at which the breakdown of a p n junction diode occurs is called the breakdown voltage. the breakdown voltage depends on the width of the depletion region, which, in turn, depends on the doping level. N type semiconductor. examples of pentavalent electrons of the impurity atom(antimony) forms cova ent bond with the four intrinsic semiconductor atoms. the fifth electron is loosely bound to the impurity atom. this loosely bound electron can be easily excited from the valance.
