A. Diode symbols and various regions in an unbiased p-n junction is shown in the attached figure. A PN junction is the simplest form of the semiconductor diode. B. Note:- I have written an interesting article which tells the story behind invention & discovery of PN Junction diode. D. Path In ideal conditions, this PN junction behaves as a short circuit when it is forward biased, and as … Dictionary ... An electronic device with two electrodes, as either an electron tube with an anode and a cathode or a transistor with a pn junction, used mainly as a rectifier since it conducts current in only one direction. In other words, the barrier in which the charge carrier stopped by the obstructive force is known as the potential barrier. Potential Barrier in a Diode Definition: The potential barrier in the PN-junction diode is the barrier in which the charge requires additional force for crossing the region. Depletion region - definition Depletion region is a region near the boundary of a p-n junction region. Due to this characteristic, the diode finds number of applications as given below: Rectification; The conversion of alternating current into direct current is known as rectification. The junction diode characteristics typically allow it to conduct current easily in one direction but not the other. This lowers the potential on the p-side of the junction relative to the n-side of the pn junction. p-n junction synonyms, p-n junction pronunciation, p-n junction translation, English dictionary definition of p-n junction. PN junction Diode plays a vital role in our electronic fields, because of their unique property (current flows in only one direction) they are used in many electronic or electrical circuits like rectifiers, switches, clippers, clampers, voltage multipliers.. Barrier. P-N Junction: P-N junction diode is the most fundamental and the simplest electronics device. PN Junction Diode Multiple Choice Questions Answers; 1. Operating junction temperature(T J):-the highest tolerable temperature for the diode’s PN junction, usually given in degrees Celsius (o C) if junction temperature reaches more than the highest limit of diode then thermal break down happens. Dictionary ! When one side of an intrinsic semiconductor is doped with acceptor i.e, one side is made p-type by doping with n-type material, a p-n junction diode is formed. A junction diode is a semiconductor crystal, usually made of silicon, with two electrical terminals attached.A P-N junction diode is the most common type of semiconductor diode. In a PN junction with no external voltage, the electric field between acceptor and donor ions is called a. PN junction diodes can be obtained in a number of semiconductor materials - the earliest diodes tended to be made from germanium, but most of them today are silicon diodes. Region: A specified district or territory. Menu. The line dividing the two regions, where N D - N A = 0, is the metallurgical junction. Define p-n junction. A PN junction with two metallic contacts is known as a pn junction diode or a semiconductor diode. Peak. A p-n junction diode allows electric current when it is forward biased and blocks electric current when it is reverse biased. C. Threshold.
