most diodes are made of silicon, but other semiconducting materials such as gallium arsenide and germanium are also used. The obsolete thermionic diode is

primitive Schottky diodes. When sufficient forward voltage is applied, a current flows in the forward direction. A silicon p–n diode has a typical forward

SYDAC (silicon thyristor for alternating current), bi-directional thyristor breakover diode, or more simply a bi-directional thyristor diode, it is technically

diode and acts more like a gas-discharge tube replacement. Avalanche diodes have a small positive temperature coefficient of voltage, whereas diodes relying

present in Zener diodes with the Zener effect predominating at lower voltages and avalanche breakdown at higher voltages. Zener diodes are used to generate

including vacuum tube diodes, wet chemical cells, mercury-arc valves, stacks of copper and selenium oxide plates, semiconductor diodes, silicon-controlled rectifiers

The 1N4148 is a standard silicon switching signal diode. It is one of the most popular and long-lived switching diodes because of its dependable specifications

samples (immunoassay), and pulse oximeters. PIN diodes are much faster and more sensitive than p–n junction diodes, and hence are often used for optical communications

of p-n junction diodes, but the techniques may be generalized to other solid state diodes. The Shockley diode equation relates the diode current I {\displaystyle

single IMPATT diodes can produce continuous microwave outputs of up to 3 kilowatts, and pulsed outputs of much higher power. These diodes are used in a
