The 2SC1359 named in this 55.6 KB PDF is, by its 2SC prefix, a Japanese-standard NPN bipolar transistor, so despite the schematic label the document should be a…

PDF document for the 2SA1635, filed under schematics but in fact a component sheet for a discrete transistor; the _1-2 suffix in the name likely marks a part or revision…

A PDF document for the 2SA1604, an 84 KB file listed in the index as a schematic but named after a single discrete part rather than a board.

Component sheet for the 2SA1723, an 80.1 KB PDF. The name holds only the part number, so no equipment model or board revision can be attached to it.

Combined PDF of 49.6 KB whose name covers both 2N5550 and 2N5551, followed by a trailing 3 that may be an edition number but is not explained.

Catalogued as a schematic, the 1SR139 document comes as a 117 KB PDF whose name mentions 400 and 600 variants, so it likely covers two grades of one discrete part.

The name 31DQ05 suggests a discrete diode part number, so this 75.9 KB PDF, although catalogued as a schematic, is probably a single-part datasheet.

Catalogued as a schematic, this 77.1 KB PDF named 30SLJQ060 carries a discrete rectifier style part number, so treat it as a component datasheet.

Indexed under schematics, this 106 KB PDF is named only 30BQ060, a code that looks like a discrete component part number, so expect datasheet-style pages rather than a…

Schematic in PDF form, 1.32 MB, for the UL20A according to its short name. No revision or board number beyond that code is stated, so read the cover page to confirm the…
