Largest sheet in this group at 469 KB, this PDF for the 2N5962 is listed as a schematic, though it is likely a detailed datasheet with graphs. The name carries only the JEDEC part number. The 2N prefix covers two-junction discrete semiconductors. A sheet like this lets a technician identify pins and check gain, noise or voltage limits. It also shows the case outline, so you can confirm a replacement is a true equivalent rather than just a close number.
