The 2SD2201 is the subject of this 153 KB PDF, indexed as a schematic though the content is presumably a datasheet.

Transistor datasheet PDF for the 2SC3265, 189 KB in size and filed as a schematic. The 2SC prefix follows the JIS standard and indicates an NPN device; the name does not…

Datasheet for the 2SD1427 NPN bipolar transistor, a compact 66 KB PDF from the Japanese 2SD numbering family.

A 120 KB PDF for the 2SK1578, an N-channel FET according to its Japanese 2SK designation.

Datasheet for the 2SC5275 NPN transistor, supplied as a 137 KB PDF and catalogued under schematics.

Short 46 KB PDF named only 2SD1651, classified as a schematic but almost certainly the datasheet for this NPN bipolar transistor from the 2SD family.

The 2SD2624 is described in this small PDF of 30.0 KB, indexed under schematics, though a part number like this generally indicates a datasheet.

A 112 KB PDF datasheet for the 2SK2627, catalogued as a schematic. Following JIS numbering, 2SK identifies an N-channel FET, so the file describes one discrete device…

PDF reference of 286 KB for the 2SJ105, listed in the schematic section. Japanese JIS semiconductor codes beginning with 2SJ denote P-channel FETs, pointing to a…

Covering the 2SC4523, this 90.3 KB PDF is a semiconductor data sheet rather than a board schematic, despite its catalogue category.

PDF of 105 KB for the 2SA1606, indexed among schematics yet covering a single semiconductor.

PDF titled BQ738, which matches the naming of Texas Instruments bq738xx battery charge controllers common on laptop boards.

Datasheet PDF, 63.9 KB, for the 2SD2211, filed in the schematic category. Japanese JIS numbering places 2SD parts among NPN bipolar transistors intended for…

Datasheet PDF, 392 KB, for the 2SK2992. The 2SK prefix belongs to the Japanese JIS registration for N-channel FETs, so despite the schematic category this describes one…

The 2SK2963 is covered by this 323 KB PDF, named only by part number. That 2SK prefix follows the JIS convention for N-channel field-effect transistors, pointing to a…

A 120 KB PDF for the 2SK2083, indexed under schematics but most probably the component datasheet.

A 36.2 KB PDF documenting the 2SK1610, an N-channel field-effect transistor as indicated by its Japanese 2SK prefix.

PDF documentation for the 2SD1090 transistor, 198 KB, catalogued under schematics though the name indicates a component datasheet.

Named simply 2SC4636, this 103 KB PDF documents that Japanese-standard NPN transistor and is most likely its datasheet. The name gives no appliance or board reference.

A 180 KB PDF named after the 2SC5255 NPN transistor and catalogued as a schematic, though it is most likely a component datasheet.

A 94.1 KB PDF labelled 2SC4272, sitting in the schematic category but carrying only a part number, so it is probably the datasheet for that transistor.

For the 2SC5703 there is this 167 KB PDF, catalogued as a schematic but almost certainly a part datasheet, since 2SC denotes an NPN bipolar transistor in the JIS system.

A 281 KB PDF referencing the 2SC2644 transistor, catalogued among schematics but most likely its datasheet.
