1. Domestic semiconductor devices The model consists of five parts
The first part: Arabic numerals indicate the number of electrodes of the device
The second part: Chinese phonetic letters indicate the material and polarity of the device
The third part: Chinese phonetic letters indicate the type of device
The fourth part: Arabic numerals indicate the serial number
The fifth part: Chinese phonetic letters indicate the specification number
Note: The model names of field effect devices, special semiconductor devices, composite tubes, PIN-type tubes, and laser devices only have the third, fourth, and fifth parts.
2. Semiconductor devices The symbols and meanings of the components are as follows: Table 1 Nomenclature of domestic semiconductor devices
