PDF for the IRF540 MOSFET, and the name indicates the datasheet comes from Philips. Although listed under schematics, the 91.6 KB file is a component sheet with ratings…

Datasheet for the 2SD2258 NPN bipolar transistor, supplied as a 56.8 KB PDF and filed under schematics.

Covering the 2SD1817, this 75.8 KB PDF is indexed as a schematic but by name is a component datasheet. No maker or revision is indicated.

For the 2SD2098 transistor, this 159 KB PDF is categorised as a schematic but follows the usual naming of a part datasheet.

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

Datasheet-style PDF for the 3LP02N, about 41.5 KB and listed as a schematic. No device, brand or board details appear in the name beyond the part code itself.

Datasheet-style PDF for the 2SD1994A transistor, filed in the schematic category of the index.

Datasheet PDF, 43.0 KB, for the 2SD2321, with an _E suffix carried over from the original name, though the suffix itself is not explained.

The 34.0 KB PDF named 2SK3557 is indexed as a schematic, but its name is a JIS component number, so it is almost certainly a datasheet.

The 2SK2792 part number appears here with an unexplained 1-5 suffix, possibly a page range or edition marker.

Here the 2SK2746 is documented in a 420 KB PDF, categorised as a schematic yet named like a single-part datasheet.

Covering the 2sk2580, this 34.5 KB PDF is labelled a schematic yet identifies only a semiconductor part, pointing to a short datasheet.

The 2SK2545 is the subject of this 415 KB PDF, catalogued as a schematic but by its name a discrete transistor document.

PDF for the 2SK2463 carrying a _1-5 suffix, 136 KB in size; the name does not explain the suffix, which may refer to pages or an edition of the document.

PDF reference for the 2SK2339 transistor, 35.9 KB, catalogued under the schematic type.

Short PDF of 23.2 KB named for the 2SK2324 part. In JIS nomenclature 2SK denotes an N-channel FET, so this schematic-labelled file is presumably a brief datasheet.

The 2SK2010 transistor is documented in this 90.1 KB PDF, filed among schematics but in substance a datasheet for an N-channel FET, as the JIS 2SK prefix indicates.

Part-number PDF for the 2SK1471, 92.5 KB in size and labelled as a schematic in the index.

The 2SK1375 N-channel field-effect transistor is covered by this 150 KB PDF, filed under schematics in the catalogue.

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

The 2SJ511 named in this 417 KB PDF is a JIS-coded semiconductor, the 2SJ prefix signalling a P-channel field-effect transistor.

PDF document for the 2SJ346, filed in the index as a schematic but named after a discrete semiconductor part.

Small 89.2 KB PDF labelled 2SJ191, a JIS designation that marks a P-channel FET, so the file is presumably that part's datasheet rather than a board schematic.

An 82.4 KB PDF bearing only the part number 2SJ188; the 2SJ prefix in Japanese numbering denotes a P-channel field-effect transistor, so this is likely its datasheet…

The 2SC4690 is the subject of this 175 KB PDF, which the index files as a schematic even though the name points to a single transistor document.

Here is a 42.3 KB PDF for the 2SC5264LS, indexed as a schematic. JIS numbering makes the 2SC prefix an NPN bipolar transistor, and the LS letters identify a variant of…

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…

A 39.6 KB PDF for the 2SC5216, with an _E tag in the name that is not explained. It is listed as a schematic, but the name points to a transistor datasheet.

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

The 2SC5144 is the only detail this 206 KB PDF name carries; despite the schematic label it is presumably the device datasheet for that transistor.

A 42.8 KB PDF for the 2SC5639, placed under schematics although its name is a bare part number pointing to a transistor datasheet.

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.

Despite sitting in the schematic category, this 99.9 KB PDF is named after the 2SC4164 and should therefore contain transistor specifications rather than a circuit…

The name of this 156 KB PDF is just the part number 2SC4134, so despite its schematic label it should be the datasheet for that transistor.

A 475 KB PDF referencing the 2SC5092 transistor type; the 2SC prefix denotes an NPN bipolar device under the Japanese JIS numbering system.

Brief 35.7 KB PDF covering the 2SC5536 NPN transistor, filed as a schematic in the index.

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.

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.
