Packaging classification of diode and triodes of electronic components

There are many types of diode and transistor, and it is difficult to distinguish them. Here are the classifications:

First of all, we can divide from packaging materials: glass diode and plastic diode; from semiconductor materials: can be divided into germanium material diode and silicon material diode; from function points: switching diode, rectifier diode, and light emitting diode.

Different semiconductor materials have different characteristics, generally switching diode are used

Germanium diode, rectifier diode, and light-emitting diode are mostly silicon diode. Generally, germanium diode are packaged in glass, and silicon diode are packaged in plastic.

Diode are distinguished by polarity. Generally, the negative pole of a diode is marked with a white, red or black color ring, and light-emitting diode-generally use extended lengths.

To distinguish the polarity at the same time, the default preset is termination

To distinguish the polarity at the same time, the default preset is termination

The classification of triode can be divided into triode according to the processing technology of triode

Divided into NPN tube, PNP tube, MOS tube.
