Only the JEDEC part number 2N5460 is given for this 115 KB PDF, listed as a schematic. The same size as the 2N5461 and 2N5462 files suggests a shared family datasheet, and a revision-tagged copy also exists in the index. Content should cover lead order, case style and electrical limits of the discrete device. It is useful for in-circuit testing, orientation checks and finding equivalents. Because no board, maker or revision is stated, confirm the marking on your component first.
