Manufacturer List Description A diode is a two-terminal electronic component that conducts current primarily in one direction resistance; it has low in one direction, and high resistance in the other. A semiconductor diode, the most common type today, is a crystalline piece of semiconductor material with a p—n junction connected to two electrical terminals.
Today, most diodes are made of silicon, but other materials such as selenium and germanium are sometimes used. As such, the diode can be viewed as an electronic version of a check valve.
This unidirectional behavior is called rectification, and is used to convert alternating current AC to direct current DC. Forms of rectifiers, diodes can be used for such tasks as extracting modulation from radio signals in radio receivers.
However, diodes can have more complicated behavior than this simple on—off action, because of their nonlinear current-voltage characteristics. Semiconductor diodes begin conducting electricity only if a certain threshold voltage or cut-in voltage is present in the forward direction a state in which the diode is said to be forward-biased.
The voltage drop across a forward-biased diode varies only a little with the current, and is a function of temperature; this effect can be used as a temperature sensor or as a voltage reference.
These techniques are used to create special-purpose diodes that perform many different functions. For example, diodes are used to regulate voltage Zener diodes , to protect circuits from high voltage surges avalanche diodes , to electronically tune radio and TV receivers varactor diodes , to generate radio-frequency oscillations tunnel diodes, Gunn diodes, IMPATT diodes , and to produce light light-emitting diodes.
