The 2SK601 is the only information in the name of this 33.2 KB PDF, which is filed under schematics yet most likely contains a datasheet, as 2SK numbers designate…

Documentation for the 2SJ378 P-channel FET in a 418 KB PDF, listed as a schematic though really a datasheet.

Compact 40.0 KB PDF for the 2SJ348, filed as a schematic but by its part number a datasheet. Under the Japanese JIS designation, 2SJ marks a P-channel FET.

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

PDF of 162 KB containing information on the 2SD1224, categorised as a schematic. The 2SD prefix is the JIS designation for NPN transistors aimed at low-frequency…

PDF of 119 KB for the 2SD1207, categorised as a schematic though its name is a JIS transistor number.

This 234 KB PDF covers the 2SC4738F, indexed as a schematic though it concerns one transistor.

Close in number to its neighbours, 2SC4645 is another JIS-coded NPN transistor, and this 147 KB PDF is probably its datasheet.

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…

A 136 KB PDF for the 2SC4616, listed among schematics though the name only carries a component part number, implying a transistor datasheet.

Small 92.6 KB PDF bearing only the part number 2SC4219. Although the catalogue lists it as a schematic, the 2SC prefix, the JEITA code for an NPN bipolar transistor…

PDF document of 331 KB named after the 2SC4116 part number, filed in the index under schematics.

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.

Datasheet-style PDF of 181 KB for the 2SC5819 transistor, listed under schematics in the index.

Documentation for the 2SC5548 NPN bipolar transistor, a 231 KB PDF catalogued under schematics, with a separate 2SC5548A variant also present in the collection.

PDF datasheet, 41.0 KB, for the 2SC5506 NPN bipolar transistor, held in the schematic section.

Concerning the 2SC5452, this 42.4 KB PDF is listed as a schematic but, judging by size and part number, is a component datasheet for an NPN transistor in the Japanese…

At 214 KB, the 2SC3964 PDF is one of the larger files in this group, likely a full datasheet with characteristic curves for this JIS-numbered NPN bipolar transistor…

Datasheet for the 2SC3939 transistor in a 51.2 KB PDF, catalogued as a schematic; the _E ending likely marks an English-language release, though the name does not…

At 168 KB, this PDF for the 2SC3925 is larger than most in the series, likely holding characteristic curves or extra package data.

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

Indexed as a schematic, this 96.7 KB PDF is named for the 2SC3086 and most likely holds that transistor's datasheet.

Datasheet-type PDF of 197 KB for the 2SA2069 transistor, indexed under schematics. Following JIS naming, the 2SA prefix identifies a PNP transistor intended for…

Small 41.7 KB PDF for the 2SA1961, with an unexplained E suffix that may mark a document edition.

Covering the 2SA1242, this 212 KB PDF carries only the part number in its name, so it is best treated as the component datasheet despite the schematic label.

Covering the 2SA1905, this 213 KB PDF is listed under schematics, yet the name gives only the component code, so it most likely contains the datasheet.

For the 2SA1213 there is this 224 KB PDF, categorised as a schematic, though the part-number-only name points to a component datasheet.

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.

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.
