Filed as a schematic, this 53 KB PDF is named after the 2SD1725 part number, so it is most likely a component datasheet rather than a board diagram.

Labelled 2SD1997, this 86.1 KB PDF is indexed as a schematic, yet a bare transistor part number points to a manufacturer datasheet.

At just 33.5 KB, this PDF for the 2SD1623 is a short document listed as a schematic, though the part-number name suggests a compact datasheet.

Datasheet-style PDF for the 2SD1423, 41.0 KB, stored as a schematic; the trailing _E in the name is not explained by the file itself.

Datasheet-type PDF for the 2SD1878, 90.6 KB, placed in the schematic category of the index. The name contains nothing beyond the part number.

Small PDF of 92.1 KB filed under schematics, though its name is simply the part number 2SD1998, so it is almost certainly a component datasheet rather than a board…

A 115 KB PDF named after the 2SD1625 part number, catalogued as a schematic but in practice most likely the transistor's datasheet.

PDF of 77.6 KB named 2SD1620 and filed with schematics; the name carries nothing beyond the part number, which points to a component datasheet.

The 2SD1908 transistor is documented in this 85.8 KB PDF, which the index files as a schematic, although a JIS part number like this normally indicates a datasheet.

The name 2sd1455 refers to a JIS-registered NPN transistor, and this 53.0 KB PDF is most likely its manufacturer datasheet, although the index lists it as a schematic.

Document for the 2SD1624, a PDF of 144 KB stored in the schematic section; with only a part number in the name it should be treated as a datasheet.

Indexed as a schematic, this PDF is named 2SD1459, a Japanese JIS designation that points to a datasheet for an NPN transistor rather than a board diagram.

Datasheet-style PDF of 83.8 KB named for the 2SD1940, an NPN transistor under Japanese JIS numbering, in which 2SD stands for NPN low-frequency types.

The 2SD1907 is covered by this 165 KB PDF, which is catalogued as a schematic but by name is a component datasheet.

Schematic in PDF for the NEC LaVie S LS150SSB, built on Quanta project FF6, board DA0FF6MB6D1, roughly 3.06 MB.

Schematic for HP Pavilion G4, G6, G7 and DV6 laptops built on the Quanta R18D board, numbers DAR18DMB6D1 and DAR18DMB6D0, in a 967 KB RAR.
