n {\displaystyle n} is the ideality factor, also known as the quality factor, emission coefficient, or the material constant. The equation is called the Shockley ideal diode equation when the ideality factor equals 1, thus is sometimes omitted. The ideality factor typically varies from 1 to 2 (though can in some cases be higher), depending on ...
The Shockley diode equation relates the diode current of a p-n junction diode to the diode voltage .This relationship is the diode I-V characteristic: = (), where is the saturation current or scale current of the diode (the magnitude of the current that flows for negative in excess of a few , typically 10 −12 A).
Electron flow is the reverse of conventional current flow. [1][2][3] A diode is a two- terminal electronic component that conducts current primarily in one direction (asymmetric conductance). It has low (ideally zero) resistance in one direction and high (ideally infinite) resistance in the other.
Breakdown voltage is a characteristic of an insulator that defines the maximum voltage difference that can be applied across the material before the insulator conducts. In solid insulating materials, this usually [citation needed] creates a weakened path within the material by creating permanent molecular or physical changes by the sudden current.
Diode logic. Simple encoder in diode logic outputting a 3-bit binary index for a single High input. Diode logic (or diode-resistor logic) constructs AND and OR logic gates with diodes and resistors. An active device (vacuum tubes with control grids in early electronic computers, then transistors in diode–transistor logic) is additionally ...
Pin configuration. anode and cathode. Electronic symbol. The Schottky diode (named after the German physicist Walter H. Schottky), also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action.
p–n junction. Pin configuration. A: Anode, K: Cathode. Electronic symbol. A p–n diode is a type of semiconductor diode based upon the p–n junction. The diode conducts current in only one direction, and it is made by joining a p -type semiconducting layer to an n -type semiconducting layer.
1N400x rectifier diode. 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 common household appliances. Its blocking voltage varies from 50 volts (1N4001) to 1000 volts (1N4007). This JEDEC device number series is available in the DO-41 axial ...
