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

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.

Small 44.3 KB PDF describing the 2SC5419, with the _E suffix seen across this series. It sits in the schematic category, yet the name is a JIS transistor number: 2SC…

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.

2SC3789 is the sole identifier on this 157 KB PDF, placed in the schematic section of the index.

Labelled 2SC4835 with an _E suffix, this 41.5 KB PDF is filed as a schematic but refers to a JIS-numbered NPN transistor, indicated by the 2SC prefix.

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

The 2SC3116 NPN transistor is described in this 47.6 KB PDF, placed in the schematic category.

Small 42 KB PDF for the 2SC3077, filed as a schematic. The trailing _E in the name is not explained by the file name itself.

Catalogued as a schematic, this 190 KB PDF is named after the 2SC2999, a part number in the Japanese JIS scheme where the 2SC prefix marks an NPN bipolar transistor.

Reference document for the 2SC1815, a 310 KB PDF classed as a schematic. In JIS numbering the 2SC prefix denotes an NPN bipolar transistor, and the file is most likely…

Short PDF of 50.8 KB for the 2SC1509, with an _E suffix in the file name, listed in the schematic section.

A 29.2 KB PDF carrying the part number 2SB1683, a PNP transistor by Japanese JIS naming; though labelled as a schematic, it is expected to be the component datasheet.

Datasheet covering the 2SB1592 PNP transistor in a compact 38.9 KB PDF; the _E tag likely indicates the English version of the document.

Reference document for the 2SB1398 transistor, with an _E suffix in the name that is not explained and may indicate an edition or language version.

At 249 KB this PDF is the largest in the group and covers the 2SA1618, indexed as a schematic but in practice a transistor reference.

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.

A compact 37.5 KB PDF carrying the name 2SA2044, a Japanese JIS transistor number in which 2SA stands for a PNP bipolar type.

Small 30.2 KB PDF for the 2SA1968LS, a variant of the 2SA1968 identified by the LS suffix; what that suffix denotes is not explained in the name and should be confirmed…

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

The 2SA1202 is covered by this 112 KB PDF, which the index lists as a schematic; with only the part code in the name, it is most likely the component datasheet.

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…

Component sheet for the 2SA1866 PNP bipolar transistor, stored as a 55.4 KB PDF. The 2SA prefix follows Japanese JIS conventions for PNP devices.

A 64 KB PDF covering the 2N7218, indexed as a schematic though the file name is a plain JEDEC part number and the content is most likely a single-device datasheet.

Very small PDF of 26.3 KB named with the part number 2N5639 and nothing else. Listed as a schematic, it is most plausibly a short datasheet, since 2N codes are JEDEC…

A 90.8 KB PDF titled only with the part number 2N5550, so no board, laptop model or revision can be matched.

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

Reference PDF for the 2N5088, 282 KB, with an RE suffix in the name whose meaning is not stated and may mark a revised or alternate edition of the document.

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.
