Used as zener diodes in voltage stabilizing circuits. There are some important applications of PN junction diode which are given below. The P-N junction diode has many applications. The PN junction diode has the following important applications are given below, PN junction diode is used as a voltage doubler, tripler, quadrupler in voltage multiplier circuits. Difference between series circuit and parallel circuit, Introduction of CRO (cathode ray oscilloscope), Construction and working of RVDT (Rotary variable differential transformer). It can also be used as a solar cell. For example, if N-type is considered, the excess of holes that enter into N-type after applying forward bias, adds to the already present minority carriers of N-type material. The Zener diode is made up of silicon material. The m… Due to this characteristic, the diode is used in the application like; It is a special type of diode which operates in the breakdown region. It is used as a rectifier in DC power supply. They are used as clipper to clip the portion of AC. The main application of p-n junction diode is in rectification circuits. This action of p-n junction diode enables us to use it as a rectifier. When the voltage is applied, due to the forward biased condition, the majority carriers of one side move towards the other. As High Voltage Rectifier– The large width of the intrinsic layer allows the ability to the diode to tolerate high reverse voltage without the breakdown of the diode. The circuit connection for determining the V-I characteristics of a pn junction is shown in the figure below. Variations in doping agents, semiconductor materials, and manufacturing techniques have made it possible to produce diodes that can be used in many different applications. 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. A zener diode when reverse biased can either undergo avalanche break down or zener break down. One type that is used for a variety of circuits is the PIN diode. The signal from ac mains is fed into a step down transformer T which makes it available at the terminals X and Y. 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. Your IP: 149.56.22.10 2. Cloudflare is unable to establish an SSL connection to the origin server. PIN diode has three layers where PN junction diode has only two layers. A p-n junction diode allows electric current when it is forward biased and blocks electric current when it is reverse biased. By manipulating this non conductive layer, p-n junctions are commonly used as diode: circuit elements that allows a flow of electricity in one direction but not in other (opposite) direction. The diode is a unidirectional two-terminal device that only allows flowing the current in one direction and blocks the current in another direction. However, there are times when you might have an AC power point but need to connect a device that requires a DC. Due to above fact, PN junction diode has many applications as outlined below. In clipping and clapping circuits it is used for wave shaping. The load resistance RLis connected to these terminals through a p-n junction diode D. The potential at terminal X with respect to Y will vary as a sine function with time. Additional troubleshooting information here. PN JUNCTION APPLICATION. Volt-ampere (V-I) characteristics of a pn junction or semiconductor diode is the curve between voltage across the junction and the current through the circuit. Until now, we have mentioned only one application for the diode-rectification, but there are many more applications that we have not yet discussed. Biasing means applying external voltages to the device, biasing of a PN Junction diode is of two types: Forward Biasing and other one is Reverse Biasing. Rectifier Diode. It allows the current to flows both in the forward as well as in the reversed direction, when the Zener voltage is reached. A diode’s standard working depends on the interaction of n-type semiconductor and p-type semiconductors.. N-type Semiconductor Here we will discuss the working of Zener diode as voltage regulator. The forward biased PN junction diode is used as LED. PN junction diode can be used as solar cells. Application of a Junction Diode as a Rectifier The concept of Direct Current and Alternating Current is not alien to many. Additional troubleshooting information here. Devices, invariably have clear instructions about using AC/DC current. It appears that the SSL configuration used is not compatible with Cloudflare. It appears that the SSL configuration used is not compatible with Cloudflare. PN junction diode is used as a voltage doubler, tripler, quadrupler in voltage multiplier circuits. Zener Diode is a special purpose PN junction diode its construction is similar to a conventional PN junction diode. Simulation using Multisim of PN Junction Diode Characteristics. Most of the diodes allow the flow of current in one direction but some diodes like Zener Diode allow the flow of current in both directions. 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. By manipulating this non-conductive layer, p–n junctions are commonly used as diodes: circuit elements that allow a flow of electricity in one direction but not in the other (opposite) direction. PN Junction Diode are used in many application like: PN Junction Diodes are mostly used for rectification (Alternative Current to Pulsating DC). Diode rectifier gives an alternating voltage which pulsates in accordance with time. PN junction diode is a diode which can be used as a rectifier, logic gate, voltage stabiliser, switching device, voltage dependent capacitor and in optoelectronics as a photodiode, light-emitting diode (LED), laser diode, photo detector, or solar cell in electronics. symbol of all types of diode. ; It is used as a rectifier in DC power supply.
