Before the development of silicon semiconductor rectifiers, vacuum tube thermionic diodes and copper oxide- or selenium-based metal rectifier stacks were used. [1] The first vacuum tube diodes designed for rectifier application in power supply circuits were introduced in April 1915 by Saul Dushman of General Electric.
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 .
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 ...
Selenium Rectifier. 8-plate 160V 450mA Federal-brand. A metal rectifier is an early type of semiconductor rectifier in which the semiconductor is copper oxide, germanium or selenium. They were used in power applications to convert alternating current to direct current in devices such as radios and battery chargers.
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.
The use of the metal–semiconductor diode rectifier was proposed by Lilienfeld in 1926 in the first of his three transistor patents as the gate of the metal–semiconductor field effect transistors. [11] The theory of the field-effect transistor using a metal/semiconductor gate was advanced by William Shockley in 1939.
International Rectifier was an American power management technology company manufacturing ... as a part of Infineon Technologies' overall semiconductor portfolio ...
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
