Avalanche diode is a transistor that can generate high-frequency oscillations under the action of an applied voltage.
Schottky Barrier Diode is a diode with Schottky characteristics and a "metal semiconductor junction"
According to the construction classification, semiconductor diodes mainly rely on PN junctions to operate.
Alloy diodes are formed by fabricating PN junctions on N-type germanium or silicon single crystal wafers by alloying with metals such as indium and aluminum.
Alloy diffusion diode is a type of alloy type. Alloy materials are easily diffused materials.
Crystal diodes can generally be used for over 100000 hours. But if used improperly, it cannot fully function and may even be quickly damaged.
