I recently purchased a 'grab bag' of components which included a bunch of transistors. Most of the transistors are what I think of as a typical transistor, black case, flat on one side. Many of these transistors have no markings on them at all. Others say things like "NTCMP S3706" or "NTC P N4916". Is there a reasonable way to learn more information about the specifications for these transistors?
Thanks.
