Schottky diode is another kind of typical semiconductor diode, its distinctive feature is a small voltage drop in the direct inclusion. It got its name in honor of the inventor of the German physicist Walter Schottky. These diodes as a potential barrier are applied as metal-semiconductors, not in p-n junction.
The switching diodes are designed for use in switching microwave signal devices (protective devices, such as switching devices “transmit / receive” in the scanned array antennas, etc.). The operation of such diodes based on the change of the impedance at the signal frequency depending on the magnitude and polarity of the bias voltage. The switching diodes are of two types – the resonant structure and pin.
A diode is a 2-electrode electric vacuum, semiconductor or gas-discharge device with a one-way conduction of electric current: it well passes through a current in one direction and very badly in the other. This basic property of the diode is used, in particular, for converting alternating current power into direct current.
