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…

Small 67.8 KB PDF for the 2SD1854, a part number in the Japanese 2SD series of NPN bipolar transistors, so it is really a datasheet rather than a full schematic.

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

Component reference for the 2SD2635, a 35.2 KB PDF listed among schematics. The file name offers only the part number, with no manufacturer or revision given.

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.

PDF document of 41.0 KB for the 2SD2185 transistor, with an _E suffix in the file name that is not decoded here.

Small 56.9 KB PDF for the 2SD1679, with an extra E suffix in the name that is not explained further.

Datasheet-style PDF for the 2SD1423, 41.0 KB, stored as a schematic; the trailing _E in the name is not explained by the file itself.

Reference sheet for the 3SK143, delivered as a 35.1 KB PDF and indexed under schematics. Beyond the part number the name says nothing.

A 32.8 KB PDF for the 3SK273, indexed as a schematic though it is likely a manufacturer datasheet.

Reference PDF for the 3N255, sized at 42.2 KB and catalogued among schematics, though nothing beyond the part number is given in the name.

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

PDF document of 299 KB named for the 2SK117, most likely a datasheet even though the catalogue lists it as a schematic.

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.

Part documentation for the 2SK2914 in PDF form, 396 KB, placed in the schematic section of the index.

A 318 KB PDF covering the 2SK2882, listed under schematics but almost certainly a datasheet given the bare part number in its name.

Covering the 2SK2865, this 424 KB PDF sits in the schematic category but, judging by its name, is the component datasheet.

For the 2SK2744 this 177 KB PDF provides component-level reference material, although the index lists it among schematics.

PDF of 410 KB for the 2SK2717, recorded as a schematic but named after a single semiconductor part.

Part reference for the 2SK2607, an N-channel FET according to the 2SK prefix of the JIS numbering convention.

Reference sheet for the 2SK2599 in a 418 KB PDF, placed in the schematic section although the name holds nothing but the part number.

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.

Reference sheet for the 2SK2046, supplied as an 88.4 KB PDF. The 2SK designation belongs to the Japanese registration scheme for N-channel field-effect transistors…

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.

Reference PDF covering the 2SK1842, a part number in the JIS 2SK series used for N-channel field-effect transistors.

Datasheet PDF, 292 KB, for the 2SK1829 transistor. Under JIS naming, 2SK marks an N-channel FET; the file name gives only the part number, with no maker or package…

PDF, 121 KB, for the 2SK1474 transistor. Japanese 2SK numbering denotes an N-channel field-effect device, so although the index category is schematic, the content is…

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

Listed as a schematic, this 125 KB PDF is named after the 2SK1466, a part code that under the Japanese JIS scheme denotes an N-channel field-effect transistor.

This small 31.6 KB PDF bears the name 2SK1444LS and is classed as a schematic. The name links it to a suffixed variant of the 2SK1444 without saying what LS stands for.

Datasheet in PDF form for the 2SK1067, a member of the 2SK family of N-channel FETs, at 144 KB. The file carries no further details in its name.

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

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

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.

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…

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…
