I notice that smd identification tools are disappearing from the web for one reason or another.
At the same time, basic transistor functional types remain difficult to search or to compare, even as they become increasingly unobtainable due to part obsolescence.
For those interested, there are five excel spreadsheets covering work I've done in the past, compiling from various sources.
At present the markings include duplicates from differing sources that haven't yet been weeded out - only about half way through this on the mark-to-type list (the type-to-mark list is generated from the other on the file's name-date).
The bipolar listings, though far from complete (~64K lines), have various bogus part numbers (generated on the web in error or mischief) identified and removed.
See the Semiconductor Identification Tools links - they are direct downloads of the zipped spreadsheets.
