Fundamental of PN Junction Diode – Application Point of View, Use of PN Junction Diode in Rectifier, Clipper, Clamper and Multiplier Circuit. • It is used in detector and demodulator circuits. There are some important applications of PN junction diode which are given below. The PN junction diode used as varactor diodes for use in voltage controlled tuning circuits as may be found in radio and TV receivers. The positive side of a diode is known as the anode and the negative side is known as the cathode.. Current can spill out of the anode end to the cathode, but it cannot pass from cathode to the anode. It is a special type of diode which operates in the breakdown region. These circuits are used to describe the conversion of a.c signals to d.c in power supplies. Cloudflare is unable to establish an SSL connection to the origin server. PN JUNCTION APPLICATION. The way that a diode operates can be difficult to understand as it involves fairly advanced quantum mechanics.However, at the simplest level the operation of a diode can be understood by looking at the flow of positive charges (or "holes") and the negative charges (the electrons).Technically, a semiconductor diode is referred to as a p-n junction. Until now, we have mentioned only one application for the diode-rectification, but there are many more applications that we have not yet discussed. A pn junction diode is made from semiconductors like silicon or germanium where an N-type region is created with the help of negative charge carriers called n-type semiconductor while the P-type region is created with the addition of positive charge carriers called p-type semiconductors.
