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.

1N4001 diode in DO-41 axial package (through hole mount) A schematic symbol for general-purpose silicon rectifier diodes Current-voltage characteristics of a 1N4001 at different temperatures The 1N400x (or 1N4001 or 1N4000 [ 1 ] ) series is a family of popular one- ampere general-purpose silicon rectifier diodes commonly used in AC adapters for ...
An aspect of most rectification is a loss from the peak input voltage to the peak output voltage, caused by the built-in voltage drop across the diodes (around 0.7 V for ordinary silicon p–n junction diodes and 0.3 V for Schottky diodes). Half-wave rectification and full-wave rectification using a center-tapped secondary produces a peak ...
A silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state current-controlling device. The name "silicon controlled rectifier" is General Electric 's trade name for a type of thyristor .
PIN diode A multilayer semiconductor diode with a thin region of intrinsic material between its p-doped and n-doped regions. planar graph In network theory, a set of nodes and interconnecting lines that can be given in one plane without crossing lines. plasma A state of matter where electric charges are free to move. plenum cable
The major breakthrough in power semiconductor devices is expected from the replacement of silicon by a wide band-gap semiconductor. At the moment, silicon carbide (SiC) is considered to be the most promising. A SiC Schottky diode with a breakdown voltage of 1200 V is commercially available, as is a 1200 V JFET. As both are majority carrier ...
In an organic light-emitting diode , the electroluminescent material composing the emissive layer of the diode is an organic compound. The organic material is electrically conductive due to the delocalization of pi electrons caused by conjugation over all or part of the molecule, and the material therefore functions as an organic semiconductor ...
The DO-35 (also known as DO-204-AH or SOD27) is a semiconductor package used to encapsulate signal diodes (i.e., diodes meant to handle small amounts of current and voltage). [ 10 ] [ 13 ] [ 2 ] It is often used to package small signal, low power diodes such as 1N4148 (a 100 V, 300 mA silicon diode.)
