Here is a list of semiconductor prefixes.
Pro electron A... (germanium)
Prefixes in the Datenblattsammlung:AA... AC... AD... AE... AF... AS... OUTER ONE... AY...
of the manufacturers: AEG Telefunken, SIEMENS, Sescosem>sgs thomson, VALVO>PHILIPS

some also of BENTRON, FAIRCHILD, FERRANTI, GENERAL INSTRUMENT, NATIONAL SEMICONDUCTOR, SAMSUNG, SILICONIX, SPRAGUE
and for opto-electronic parts (BP...) also of SILICONE GENERAL and BENTRON
and for thyristors, triacs uww.(BT...) also of TRANSITRON
Pro electron C... (gallium arsenide)
Prefixes of the data sheet collection:

JEDEC Registration
1N.... (diodes)
In the data sheet collection of:
FAIRCHILD, GENERAL ELECTRIC>RCA, GENERAL INSTRUMENT, MOTOROLA, RCA, Sescosem>sgs thomson, SEMTECH, SOLITRON, Texas Instruments, UNITRODE
some also of CODI, GENERAL SEMICONDUCTOR, HEWLETT-PACKARD, M/ACOM, MICROSEMICONDUCTOR CORP., SEMICON, SIEMENS, SILEC, TELEDYNE, TRANSITRON, UNIZON, VALVO
2N.... (transistors)
All American manufacturers, also many European and Japanese. Before 30 years it belonged to the good clay/tone to have at least some JEDEC types in the program. In the reason it unimportant also, from which manufacturer the data sheet comes, because the uniformity was more strictly supervised, as at most other families.
3N.... (FETs, opto coupler)
