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

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

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

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.

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

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

A 92.5 KB PDF named after 2SJ256, a JIS-numbered P-channel field-effect transistor according to its 2SJ prefix.

Catalogued as a schematic, this 88.5 KB PDF is named only 2SJ230, a JIS code in which the 2SJ prefix identifies a P-channel field-effect transistor.

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…

Base-version document for the 2SC4738, a 236 KB PDF placed in the schematic category. Following the JIS scheme, the 2SC prefix denotes an NPN bipolar transistor; F and…

Named after the transistor type 2SC4646, this 148 KB PDF most likely contains the part datasheet. No board, model or revision is mentioned.

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.

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.

Bearing only the part number 2SC4393, this 319 KB PDF is indexed as a schematic yet is most likely the transistor datasheet.

Smallest of the batch at 30.8 KB, the PDF named 2SC5607 is presumably a concise datasheet for that NPN transistor despite being labelled a 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…

Catalogued as a schematic, this 100 KB PDF is named after the 2SC4031 and is most likely its datasheet. JIS numbering uses 2SC for NPN bipolar transistors.

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.

PDF component sheet for the 2SC3481, 131 KB in size and catalogued with schematics. The file name holds just the part number; the 2SC prefix is the JIS designation for…

Part number 2SC3401 is the only information in the name of this 87.3 KB PDF, so no device or board is identified.

Datasheet PDF of 172 KB carrying the part number 2SC5358, listed under schematics in the index.

Covering the 2SC5353, this 208 KB PDF sits in the schematic category but, judging by the name, documents a single transistor.

Reference document for the 2SC3112 transistor, supplied as a 257 KB PDF and filed under schematics. The name holds only the part number.

A 508 KB PDF filed under schematics, named only with the JIS part number 2SC2996. The 2SC prefix identifies an NPN bipolar transistor, so the document is probably a…

Named 2SC2859, this 192 KB PDF is indexed among schematics but probably holds the datasheet of a JIS-numbered NPN bipolar transistor, as the 2SC prefix suggests.

Named after the 2SA1537 transistor, this 41.0 KB PDF sits in the schematic category but should contain the manufacturer data for that part.

Indexed as a schematic, this 40.2 KB PDF is named 2SB1220 with an _E suffix and almost certainly contains the datasheet for that JIS transistor.

The 2SA1315 PNP transistor, per the Japanese JIS 2SA prefix, is the subject of this 220 KB PDF.

Datasheet-style PDF, 206 KB, for the 2SA1893 PNP transistor from the JIS 2SA family. Nothing in the name points to a specific device or board, so treat it as part…

Datasheet PDF of 42.2 KB for the 2SA1883, identified only by its part number. Japanese JIS numbering uses 2SA for PNP bipolar transistors, so the content describes a…

Datasheet for the 2N7053 in a 314 KB PDF, categorized with schematics. The size matches that of the 2N7052 file and both may come from a shared family document, though…

Small 27.6 KB PDF for the 2N7051, filed as a schematic but by its name a datasheet for one discrete semiconductor.

Indexed under schematics, this 26.9 KB PDF is labelled 2N6518, a JEDEC-registered discrete semiconductor designation.

Part number 2N5770 is the only detail this 296 KB PDF carries. It is listed as a schematic but names no board or laptop model.

Larger 546 KB PDF datasheet covering the 2N5400, a high-voltage PNP small-signal transistor; the size suggests a scanned or multi-part document.

Component datasheet for the 2N5366, a 60.8 KB PDF filed in the schematic category. The name gives only the part number, with no manufacturer, package or revision…

A 58.4 KB PDF that covers two JEDEC part numbers together, the 2N5088 and 2N5089, with a Sam tag in brackets whose source is not spelled out in the name.

Datasheet-style PDF of 166 KB for the 2N4125, with an RE suffix appended to the part number; the name does not explain it, so treat it as a possible alternate or revised…

PDF of 86.6 KB for the 2N4036, with an r0 tag in the name that likely marks a revision zero edition, though the file does not say so explicitly.
