Here the 2SK3285 is documented in a 48.6 KB PDF, placed in the index's schematic section.

For the 2SK2313 transistor, this 419 KB PDF is filed as a schematic but is expected to be a datasheet, since 2SK is the JIS prefix for N-channel FETs.

Part number 2SK2231 is the only information carried by this 420 KB PDF, which the index places among schematics but which most likely documents a single transistor.

PDF reference, 115 KB, for the 2SK1924 N-channel field-effect transistor; the 2SK prefix places it in the Japanese JIS transistor registry.

Part 2SK1890, documented in a 96.7 KB PDF placed in the schematic category. Japanese JIS numbering reserves 2SK for N-channel FETs, so this is a component datasheet…

PDF documentation for the 2SK1731 discrete semiconductor, roughly 90 KB in size. Japanese 2SK numbering identifies it as an N-channel FET; the name says nothing about…

The 2SK1468 transistor is covered by this 92.5 KB PDF, categorised as a schematic though the name is purely a part number.

Short 31.7 KB PDF for the 2SK1460LS, an N-channel FET by the Japanese 2SK prefix, carrying an LS suffix that distinguishes it from the plain 2SK1460 also in this index.

Datasheet-style PDF of 104 KB for the 2SK1433, placed in the schematic category of the index.

Datasheet for the 2SD1187 transistor in PDF form, 227 KB, which is larger than most sheets in this series and may include more curves or package options.

Variant documentation for the 2SC4738FT, a 138 KB PDF stored in the schematic category.

Part data for the 2SC4686A in a 208 KB PDF, catalogued with schematics. JIS numbering marks 2SC as an NPN bipolar transistor, and an A suffix normally points to a…

The 123 KB PDF bears the part number 2SC4644 and nothing else. That makes it a reference for a single NPN transistor rather than a full circuit diagram, despite the…

Here is the 2SC5242 documentation as a 173 KB PDF, placed in the schematic category but evidently a part datasheet going by its name.

Part number 2SC4454 gives this 101 KB PDF its name, and the index places it in the schematic group.

A 126 KB PDF for the 2SC5096FT, which adds an FT suffix to the base type 2SC5096. Under JEITA naming the 2SC prefix denotes an NPN bipolar transistor, and suffixes like…

Part number 2SC4207 is the sole content of this 257 KB PDF's name, which the index places under schematics.

PDF of 472 KB describing the 2SC5085 component, an NPN transistor under the Japanese 2SC numbering scheme.

A 29.5 KB PDF referencing the 2SC5792 transistor, an NPN device in the JIS-registered 2SC range.

Short 30.1 KB PDF for the 2SC5778 transistor, placed in the schematic category. Japanese JIS codes beginning with 2SC denote NPN bipolar devices, so the contents are…

A PDF for the 2SC5464FT, 125 KB, indexed as a schematic. The FT suffix appears to denote a specific package or variant of the 2SC5464 NPN transistor, but the name does…

Brief 41.9 KB PDF for the 2SC5453, in the JIS 2SC range that denotes NPN transistors. Catalogued as a schematic, it is most plausibly a short datasheet covering the…

PDF sheet titled only with the part number 2SC5022, 42.0 KB, placed under schematics. No suffix, revision or maker appears in the name.

Datasheet PDF of 125 KB for the 2SC4854, placed under schematics in the index. Only the part number is given in the name.

Catalogued among schematics, this 224 KB PDF covers the 2SC3709A transistor. By JIS convention the 2SC prefix denotes an NPN bipolar device, and the A suffix indicates a…

Specification document for the 2SC3515 transistor, a 225 KB PDF placed in the schematic category.

Indexed as a schematic, this 199 KB PDF actually carries only the part number 2SC1959, pointing to a single NPN bipolar transistor under the JIS naming scheme.

At 179 KB, this PDF for the 2SB1495 is one of the larger documents in the set and likely includes graphs alongside rating tables.

The 2sb1189 part number names this 42.5 KB PDF, which is placed in the schematic category but is most probably the transistor datasheet.

Reference sheet for the 2SB1015A, a 167 KB PDF placed in the schematic section. The Japanese JIS 2SB code designates a PNP bipolar transistor for low-frequency…

A 214 KB PDF for the 2SA1429 part, catalogued as a schematic though most likely a data sheet.

PDF reference of 43.6 KB covering the 2SA1258. No device, board or revision is mentioned, only the component code, whose 2SA prefix denotes a PNP transistor in the…

Datasheet PDF for the 2N4031 part number, 52.3 KB in size, placed in the schematic category of the index.

At 33.6 KB, this PDF named 1N746 is a short component datasheet for the original non-suffixed part of the 1N746 zener family, indexed under schematics.

Specification sheet for the 1N5283, saved as a 119 KB PDF and indexed as a schematic. Its size matches the 1N5292 file, which hints that both are the same series…

Indexed under schematics, this 181 KB PDF named 28512 most likely documents a 28-series 512 Kbit parallel EEPROM, though the name does not confirm the manufacturer or…

Schematic for a model named SL410K, supplied as a 1.58 MB PDF; the name states no brand, board number or revision, so read the title block to confirm the platform.

PDF circuit diagram, 837 KB, for the Compal LA-5752P board, marked with a (1) copy suffix and probably the same as the other LA-5752P files.
