Part reference for the 2N3416 as a 304 KB PDF in the schematic section, likely the same family datasheet shared with the 2N3417 given the identical size. The name holds no maker or revision detail. Use the document for lead identification, absolute maximum ratings and gain figures when testing or replacing this 2N-numbered transistor. Any PDF reader displays it. Where several parts share one sheet, read the values listed against 2N3416 specifically rather than the family headline.
