The 2SK1449 gives this 109 KB PDF its name, and nothing else is stated. It is filed as a schematic, though it is probably the device data sheet.

Component sheet for the 2SK1069, an N-channel FET from the Japanese 2SK numbering range, stored as a 98.7 KB PDF.

A PDF filed under schematics but named after the 2SK404, a part number in the Japanese JIS semiconductor scheme, where the 2SK prefix marks an N-channel field-effect…

Small 43.1 KB PDF for the 2SJ400, likely a short datasheet despite being indexed as a schematic.

A 92.7 KB PDF catalogued under schematics but titled only 2SJ228, a JIS-style designation used for P-channel FETs.

The 2SD1198 is the subject of this 56.6 KB PDF, filed as a schematic although the name points to a component datasheet; an _E suffix follows the part number with no…

PDF datasheet of about 56 KB for the 2SD661 transistor, with an _E suffix that probably indicates an English edition.

Small 788 KB RAR archive for the OPPO R9 smartphone. The name states only the model, and the contents, likely a handful of schematic or layout pages given the size, have…

Archive for the Huawei Y320 smartphone, ZIP format, 2.51 MB. The file name does not specify the contents, which are probably service documents such as schematics or a…

A 161 KB PDF carrying only the part number 2SC4650, a JIS-registered NPN transistor. Nothing in the name links it to a specific device, so treat it as a component…

Reference sheet for the 2SC4627, a JIS-numbered NPN transistor, supplied as a 61 KB PDF.

Catalogued as a schematic, this 184 KB PDF is named only after the part number 2SC5175, so it is most likely the manufacturer datasheet for that discrete transistor.

The 2SC5171 named in this 169 KB PDF is a JIS-style part number, where the 2SC prefix denotes an NPN bipolar transistor for high-frequency applications, so the content…

Datasheet-style PDF of 88.2 KB for the semiconductor 2SC4475, catalogued in the schematic section.

Datasheet-style PDF of 119 KB for the 2SC4401, listed in the index under schematics although the name points to a single semiconductor part.

Named only after the part 2SC4363, this 88 KB PDF is catalogued as a schematic but is most likely the manufacturer datasheet for that transistor.

A 51.7 KB PDF for the 2SC4208, with an _E suffix in the name whose meaning is not stated; it could mark an edition or language version, but that is unconfirmed.

Compact 43.3 KB PDF covering the 2SC5551, a JIS-coded NPN bipolar transistor, even though the catalogue type says schematic.

Datasheet PDF for the 2SC5537 transistor, 32.5 KB, catalogued with schematics. In the JIS scheme 2SC denotes an NPN bipolar part, so this is component data rather than a…

For the 2SC5534 transistor, this 44.8 KB PDF sits in the schematic category but, going by the JIS 2SC code for NPN bipolar devices, is the part datasheet.

Catalogued as a schematic, this 45.8 KB PDF is named after the 2SC5503, a part number in the Japanese 2SC series used for NPN bipolar transistors.

A 39.3 KB PDF for the 2SC5490 component, which belongs to the 2SC range of NPN bipolar transistors under Japanese JIS numbering.

Here is a 49.4 KB PDF for part 2SC4067, placed under schematics but named like a manufacturer datasheet.

Component reference in PDF form for the 2SC4002, 77.6 KB, filed in the schematic category.

Filed under schematics, the 2SC3993 PDF (107 KB) is far more likely a component datasheet, since the name is simply a JIS transistor part number.

A 52.6 KB PDF for the 2SC3933, labelled with an _E suffix and catalogued as a schematic.

PDF documentation for the 2SC3929 transistor, 54.1 KB, suffixed _E and filed under schematics.

The 2SC5416 base part is described in this 45.8 KB PDF, indexed as a schematic, with an LS variant held in a separate file.
