Semiconductor Device Numbering / Coding SchemesPro-Electron Or EECA Numbering Coding SystemJEDEC Numbering Or Coding SystemJis Semiconductor Device Numbering SchemeManufacturer NumbersThere are many different ways of organising a numbering scheme. In the early days of thermionic valve (vacuum tube) manufacture, each manufacturer gave a number to the types they manufactured. In this way there were vast numbers of different numbers for devices many of which were virtually identical. It soon became obvious that a more structured ap...See more on electronics-notes RP Photonics
