A device having two terminals and has a low resistance to electrical current in one direction and a high resistance in the other direction
A semiconductor device which permits current to flow in only one direction (analogous to a check valve, in fluid handling )
A two-terminal semiconductor (rectifying) device that exhibits a non-linear current-voltage characteristic The diode's function is to allow current in one direction and to block current in the opposite direction Also see rectifier
an electronic semiconductor device that predominantly allows current to flow in only one direction
a semiconductor device which allows electrical current to flow through it in only one direction
Simple semiconductor element, comparable to a valve The ideal diode is blocking electric current in one direction and conducting it in the other The real diode causes a voltage drop and energy loss in the forward direction, therefore power electronics sometimes use active diodes
a device that passes current only in one direction, sometimes called a rectifier
Two-element electron tube, which will allow more electron flow in one direction in a circuit than in the other direction; tube which serves as a rectifier
A two-terminal device that will conduct electric current more easily in one direction than in the other
Rectifier An electronic device with two wires or terminals A rectifier allows electrical current to flow through in only one direction and is used for converting alternating current into direct current Rectifiers were important for use in radios, which required direct current to power the amplifiers driving speakers or headphones
an electronic device that allows current to flow more easily in one direction than in the other direction
a semiconductor that consists of a p-n junction a thermionic tube having two electrodes; used as a rectifier
A two-electrode (two-terminal) device which allows a voltage/signal to pass through it in one direction only 2
a piece of electrical equipment that makes an electrical current flow in one direction (di- + hodos ). Electronic device that has two electrodes (anode and cathode) and that allows current to flow in only one direction, resisting current flow in the other. An applied voltage can cause electrons to flow in only one direction, from the cathode to the anode, and then back to the cathode through an external circuit. Diodes are used especially as rectifiers which change alternating current into direct current and to vary the amplitude of a signal in proportion to the voltage in a circuit, as in a radio or television receiver. The most familiar diodes are vacuum tubes and semiconductor diodes. Semiconductor diodes, the simplest of semiconductor devices, consist of two electrodes and a sandwich of two dissimilar semiconducting substances (a p-n junction). Such diodes form the basis for more complex semiconductor devices (including transistors) used in computers and other electronic equipment. Semiconductor diodes include light-emitting diodes and laser diodes; the latter emit laser light, useful for telecommunications via fibre optics and for reading compact discs
A two-terminal semiconductor device that will allow current to flow through it in only one direction With the proper voltage polarity across the device, it will act as a conductor When the voltage polarity is reversed, the device will act as a nonconductor, allowing no current to flow
the diode is the simplest and most fundamental non-linear circuit element It is a two terminal device which only allows current to flow in one direction
a component that readily passes current in one direction but opposes current flow in the opposite direction
A semiconductor junction device through which current flows normally in the forward direction, and in the reverse direction if a large voltage is applied
A semiconductor rectifying device in which the barrier between the two regions of opposite conductivity (n-type and p-type) type produces the rectification. All solar cells are junction diodes
a rectifying semiconductor device which converts electrical energy into electromagnetic radiation of a wavelength in or near the visible spectrum of light
{i} (Electronics) semiconductor diode which maintains a constant voltage due to the reverse breakdown voltage current (used mainly as a voltage regulator)
tiny semiconductor that produces radiation when an electrical current passes through it (used in fiber optics, laser printers, remote control devices, and more)
A semiconductor diode that "lases", i e when pulsed, a laser diode emits coherent light: light of essentially one wave length, in phase traveling in the same direction
Semiconductor diode that produces visible or infrared light when subjected to an electric current, as a result of electroluminescence. Visible-light LEDs are used in many electronic devices as indicator lamps (e.g., an on/off indicator) and, when arranged in a matrix, to spell out letters or numbers on alphanumeric displays. Infrared LEDs are used in optoelectronics (e.g., in auto-focus cameras and television remote controls) and as light sources in some long-range fibre-optic communications systems. LEDs are formed by the so-called III-V compound semiconductors related to gallium arsenide. They consume little power and are long-lasting and inexpensive
