There are many kinds of diodes, and there are also many different types of models. Diodes can be divided into germanium diodes and silicon diodes according to semiconductor materials; According to the die structure, it can be divided into point contact diode, surface contact diode and surface contact diode. According to the purpose, it can be divided into TVS transient suppression diode, ESD diode, Zener diode, rectifier diode, Schottky diode, fast recovery diode, ultra-fast recovery diode and so on.

Diode; A person who lacks dialectical thinking
