The 2SC4108 is the only detail this 94 KB PDF name provides, and the index files it as a schematic.

The 2SC5088 transistor is the subject of this 481 KB PDF, catalogued as a schematic though it most likely holds the component datasheet.

The 2SC5404 is covered by this 319 KB PDF, which the index files as a schematic. The name carries only the transistor number.

Datasheet in PDF format, around 93 KB, for the 2SC4910 NPN transistor of the JIS 2SC series.

For the 2SC5305? No: this 94.6 KB PDF covers the 2SC3705, an NPN bipolar transistor by its JIS designation, and is indexed under schematics.

The 2SC3040 appears in the name of this 107 KB PDF, which is indexed among schematics and probably holds that part's datasheet.

Document for the 2SC2778 transistor, a 60.1 KB PDF whose name ends with _E. The suffix may indicate an English-language edition, but the name does not confirm it.

Named for the 2SC2555, this 186 KB PDF is filed under schematics but is most likely the component's datasheet.

Named for the 2SB1676, this 53.3 KB PDF is listed as a schematic but, given the JIS 2SB prefix for PNP bipolar transistors, should actually be a datasheet for that part.

The 2SA1352 is the only identifier in this 149 KB PDF name, so treat it as the transistor datasheet even though the index calls it a schematic.

A 163 KB PDF titled with the part number 2SA1256, filed in the schematic category. The 2SA designation, part of the JIS numbering system, identifies a PNP transistor…

Reference sheet for the 2SA1814 transistor, supplied as an 84.8 KB PDF. The 2SA designation in Japanese JIS numbering means a PNP bipolar device, so the document should…

An 89.5 KB PDF giving datasheet information for the 2SA1802, a PNP bipolar transistor according to the JIS 2SA designation.

Part datasheet in PDF form, 172 KB, for the 2SA949, listed in the schematic category of the index.

Specification PDF for the 2SA1706 transistor, 140 KB, catalogued under schematics despite naming only a part.

A comparatively large 707 KB PDF filed as a schematic, named only 2N6427, a JEDEC 2N-series discrete semiconductor number.

Filed under schematics, this 65.3 KB PDF is named only for the 2N5191 part number, so it is almost certainly a component datasheet rather than a board drawing.

PDF of 129 KB titled 27C16, filed as a schematic but corresponding to an early member of the 27C EPROM family by its part number.

The 2SD592 NPN transistor is documented in this 50.3 KB PDF, which the catalogue lists as a schematic.

Component datasheet in PDF form, 57.8 KB, for the 2SD1478, though the index files it under schematics.

A 42.5 KB PDF describing the 2SK3293, listed among schematics but serving as a component datasheet.

PDF of 415 KB describing the 2SK2741, catalogued with schematics but in substance a part datasheet, as 2SK denotes an N-channel FET in JIS numbering.

Reference PDF for the 2SK2466, 424 KB in size, belonging to the JIS N-channel FET family denoted by 2SK. The name contains only the part number.

Reference sheet in PDF form for the 2SK2349, sized 54.7 KB and listed in the schematic category.

Part 2SK2162 is the only detail in the name of this 132 KB PDF, which the index files as a schematic though it is most likely a datasheet.

The 2SK2152 is covered by this 93 KB PDF, listed as a schematic but named only by its part number, so it is most likely the transistor's datasheet.

Datasheet PDF for the 2SK1771, about 305 KB in size. Under JIS conventions, the 2SK prefix identifies an N-channel FET; the file is listed as a schematic but the name…

A small 31.5 KB PDF identified only by the part number 2SK374. Under JIS numbering the 2SK series covers N-channel FETs, so the content is almost certainly a short…

A 32.0 KB PDF for part 2SJ616, placed among schematics but named like an individual transistor datasheet.

PDF reference for the 2SJ338, 113 KB, filed under the schematic category. No board number, brand or revision is present in the name.

Component datasheet in PDF form for the 2SJ284, roughly 81.4 KB. The file name names only this part, with no device, board or revision mentioned.

Filed as a schematic, this 72.9 KB PDF is titled 2SD1398; in the Japanese JIS scheme the 2SD prefix marks an NPN bipolar transistor intended for low-frequency use, so…

The 130 KB PDF titled 2SD1348 relates to a JIS-numbered NPN bipolar transistor, the 2SD series covering low-frequency types, and is expected to be a component datasheet…

An 88.9 KB PDF for the 2SD1247, indexed as a schematic although the name identifies a single semiconductor.

Covering the 2SD1193, this 135 KB PDF is indexed as a schematic but its name identifies a discrete component, so it is most likely the maker's datasheet.

At 130 KB, this PDF documents the 2SD1060, the largest of its neighbouring files and filed as a schematic. Nothing beyond the part number appears in the name.

A small 30.6 KB PDF for the 2SC4637LS. The LS suffix appears to denote a particular package or lead variant of the 2SC4637 NPN transistor, so check the outline drawing…

Covering the 2SC4612, this 155 KB PDF is indexed as a schematic but is in practice a transistor datasheet, as only the part number appears in the name.

A 172 KB PDF labelled 2SC5174, filed under schematics, though the name points to a component datasheet rather than a board drawing.

The 121 KB PDF labelled 2SC4598 sits in the schematic section, yet the name is a discrete component number, so expect a datasheet.
