At 312 KB, this PDF for the 2SD2638 is the largest in its series and is probably a full datasheet with curves and outline drawings, though it is filed under schematics.

Small 39.9 KB PDF for the 2SD2474, carrying an _E suffix whose meaning the name does not state; it may reflect a language or edition marker.

Small 45.6 KB PDF named 2SD1902, a Japanese standard transistor number; despite the schematic label it is most probably a short datasheet.

PDF document for the 2SK2374 part, filed under schematics but named after a Japanese-registered semiconductor rather than a board.

The 2SK1839 is covered in this 84.9 KB PDF, filed under schematics though the name points to a single semiconductor part.

Reference sheet for the 2SK1109, with the name indicating the UTC (Unisonic Technologies) version of the part.

Catalogued as a schematic, this 361 KB PDF carries only the part number 2SJ567 in its name.

Bearing only the part code 2SJ438, this 416 KB PDF is indexed as a schematic, yet the 2SJ prefix in Japanese JIS designation identifies a P-channel field-effect…

A compact 47.6 KB PDF called 2SD1330_E, likely the datasheet for the 2SD1330 NPN low-frequency bipolar transistor under JIS numbering, though it is catalogued as a…

Specification PDF, roughly 32 KB, for the 2SD667 transistor, listed among schematics but in fact a component datasheet.

PDF for the 2SC4417 carrying an _E suffix whose meaning the name does not explain, sized 40.7 KB.

Indexed as a schematic, this 91.5 KB PDF named 2SC4390 is most likely the datasheet of that NPN bipolar transistor.

A 107 KB PDF covering the 2SC4270, a JIS-numbered part. The 2SC prefix denotes an NPN transistor intended for high-frequency use.

Only the part number 2SC4168 identifies this 150 KB PDF, which carries a schematic label but is almost certainly a component datasheet.

Part number 2SC4157 is the only clue in the name of this 125 KB PDF, which sits under schematics but is effectively a transistor datasheet.

Specification document for the 2SC5549 transistor, a 205 KB PDF in the schematic category.

Covering the 2SC5019, this 41.9 KB PDF carries an _E suffix and is indexed as a schematic.

Reference sheet for the 2SC5411, a PDF of 311 KB catalogued as a schematic. The name gives only the part number.

Part reference for the 2SC4987, provided as a 110 KB PDF and filed under schematics. No model, board or revision is stated in the name.

Covering the 2SC3914, this 30.1 KB PDF belongs to the family of JIS-numbered NPN bipolar transistors identified by the 2SC prefix.

Catalogued as a schematic, this 87.6 KB PDF is named only with the part number 2SC3808, which follows the Japanese JIS scheme where 2SC marks an NPN bipolar transistor…

A 135 KB PDF identified only by the part number 2SC3787. While the index files it as a schematic, the JIS designation 2SC indicates an NPN bipolar transistor, which…

Datasheet-type PDF for the 2SC4787, a JIS-numbered NPN transistor, filed in the schematic category.

PDF document labelled as a schematic but named after the 2SC5387, a Japanese-numbered NPN bipolar transistor part number, so in practice it is almost certainly the…

Datasheet-type PDF of 43.3 KB for the 2SC5335, with an _E suffix that may denote an English version, though the name does not state it.

PDF document named after the 2SC5332 part number, filed here under schematics but most likely a component datasheet rather than a board diagram.

Bearing only the JIS part number 2SC2879, this 167 KB PDF is listed as a schematic. A 2SC designation marks an NPN bipolar transistor, so the file most likely contains…

A compact 33.0 KB PDF named for the 2SB647, a PNP transistor according to the JIS 2SB prefix; although indexed as a schematic, it is most likely the part datasheet.

Indexed as a schematic, this 27.0 KB PDF names the 2SB633P, a PNP transistor under JIS numbering; the P suffix is probably an hFE gain rank, a common convention for…

The 2SB1589 PNP transistor is described in this 40.1 KB PDF datasheet, with an _E suffix that most likely points to the English edition.

PDF of about 39 KB for the 2SB1462J, a variant designation of the 2SB1462, with the _E suffix likely marking English text.
