A device that allows the current to flow in only 1 direction. When a detector head is removed from its base it still passes the current. Internal connections then short it out when the detector head is back in place.
A specialized electronic component with two electrodes called the anode and the cathode; its fundamental property is its tendency to conduct current in only one direction. Most diodes are made with semiconductor materials such as silicon, germanium, or selenium. Some diodes are comprised of metal electrodes in a chamber evacuated or filled with a pure elemental gas at low pressure. Diodes can be used as lighting devices (LED's), as well as rectifiers, signal limiters, voltage regulators, switches, signal modulators, signal mixers, signal demodulators, and oscillators.
Semiconductor electronic component. Ideally, a diode conducts electricity in one direction and does not allow the current to flow in the opposite direction. Thanks to this property diodes are used to rectify alternating currents, i.e., to convert alternating current (AC) to direct current (DC).
A semiconductor device used to control the flow of electric charge. High-rated schottky diodes are used in single-direction ESCs to prevent back-EMF (voltage 'spikes') generated by the motor from entering the ESC. Report this Word Added by: rcnz
A radio valve (or tube) with only two basic electrode s, an anode and a cathode. Commonly used in radio demodulation, over- volt age protection, logic gates, and early wireless sets including ‘ cat-whisker' and thermionic valve sets.
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.
A two-terminal semiconductor device, that acts as a one-way valve which allows the electrical current to only flow in one direction. Typically a Silicon diode has a forward voltage drop of approximately 0.7 to 1.0 volt across the two terminals at full load.
An electrical circuit element that allows current to flow in one direction. Direct Current (DC) - 1.) The flow of electrons in one direction depending on the polarity of the energy source. 2.) An electrical current that flows in one direction.
This is a solid state electronic component which will allow current to flow in only one direction, similar to a check valve used in hydraulic or pneumatic applications. The diode is used in applications such as transient suppression, power supply circuits etc.
The thermionic diode invented in 1904, marks the start of the electronics era. It is the first device for controlling the flow of current in relation to applied voltage, and comprises two electrodes, the heated cathode (electron source) and anode (electron receptor).
A solid state device which allows current to pass in one direction only. Since it allows only one half cycle of an alternating current pass, its out put will be unidirectional and it may be considered a rectifying element.
An electronic device that lets current flow in only one direction. Semiconductor diodes used in fiber optics contain a junction between regions of different doping. They include light emitters ( LEDs and laser diodes) and detectors (photodiodes).
Electronic semiconductor component which lets the electrical current pass in only one direction. If a power line is compared to a water pipe, then the diode would be a (one-way) valve in the water pipe. Diodes are made of semiconductor crystals and have a typical resistance. A solar cell therefore is basically a large, illuminated diode.
An electron tube containing two electrodes: a cathode and a plate. A two element, solid-state device made of either germanium or silicon; it is primarily used as a switching device. [ Diode Manufacturers
A diode is a active circuit element (AC rectifier changing AC to DC), which is made from two different semiconductor materials bonded so as to create an interfacial junction or depletion layer between the two materials which acts like a "valve" allowing current to flow in one direction only (forward- biased case) ; whereas in the reverse-biased case the current is zero, or near zero.
In electronics, a diode is a component that restricts the direction of movement of charge carriers. Essentially, it allows an electric current to flow in one direction, but blocks it in the opposite direction. Thus, the diode can be thought of as an electronic version of a check valve.
Diode is a unique GUI library. It's really simple to use and code for, but looks great. Features: Easily customizable themes, dimming and fading, and fresh look. Seeing is believing, so check out some screens. It's pretty different.
