Various semiconductor diodes. Left: A four-diode bridge rectifier.Next to it is a 1N4148 signal diode.On the far right is a Zener diode.In most diodes, a white or black painted band identifies the cathode into which electrons will flow when the diode is conducting. Electron flow is the reverse of conventional current flow. [2] [3] [4]A diode is a two-terminal electronic component that conducts ...
Rectifier Diode: A rectifier diode is a kind of diode that is used for the rectification of alternating current (A.C). LED: LEDs are diodes used for providing light. Zener Diode: Zener diode is used for the stabilization of current and voltage in electronic systems. Photodiode: Photodiodes are used to detect light. Switching Diode: Switching diodes are used for providing fast switching in ...
Key learnings: Diode Definition: A diode is defined as a component that restricts the direction of flow of electric current, mainly allowing current to pass in one direction.; Symbol and Orientation: The diode symbol represents the direction of conventional current flow, from the anode to the cathode.; PN Junction Role: The PN junction in diodes helps form a depletion zone that acts as a ...
Diode Construction. Diodes can be made of either of the two semiconductor materials, silicon and germanium. When the anode voltage is more positive than the cathode voltage, the diode is said to be forward-biased, and it conducts readily with a relatively low-voltage drop.
Special Purpose Diodes Zener Diodes. Zener diodes are composed of heavily doped PN junction that conducts in the reverse direction when a certain specified voltage is reached. It also allows current to flow in either a forward or reversed direction. It is commonly used for surge suppressors, voltage regulation, reference elements and any other switching applications and clipper circuits.
1. PN Junction Diode. A PN junction diode is a type of semiconductor device that allows current to flow in only one direction. It consists of two regions of semiconductor material, one doped with impurities to create an excess of electrons (n-type) and the other doped with impurities to create a deficiency of electrons (p-type).
SBR uses MOSFET by making short contact between its gate and source.. SBR has a low forward voltage drop, less reverse leakage current and fast switching capability..

diode, an electrical component that allows the flow of current in only one direction. In circuit diagrams, a diode is represented by a triangle with a line across one vertex.. The most common type of diode uses a p-n junction.In this type of diode, one material (n) in which electrons are charge carriers abuts a second material (p) in which holes (places depleted of electrons that act as ...
