Zener diode is a product that replaces Zener electronic diode.
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.
