Small PDF named after the 2SC5149, catalogued as a schematic yet most likely the transistor datasheet.

Component sheet in PDF for the 2SD2248, 100 KB, which the index places among schematics. No device or board is named, just the transistor type.

PDF document, 142 KB, named for the 2SD1828, an NPN bipolar transistor going by the JIS 2SD prefix for low-frequency types.

PDF reference of 150 KB for the 2SD2206, categorised as a schematic though the name is simply a transistor number.

PDF datasheet of roughly 238 KB describing the 2SD2127 NPN transistor in the Japanese 2SD series. Although labelled as a schematic, it is a single-component reference.

Reference material for the 2SK3122 transistor in a 121 KB PDF, filed under schematics. Its size points to a fuller datasheet, perhaps with characteristic curves, though…

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

Covering transistor 2SK1417, this 101 KB PDF is filed as a schematic though the single part number suggests a datasheet.

At 383 KB, this PDF titled 2SJ104 is filed as a schematic yet most likely holds the datasheet for that part.

Part datasheet for the 2SD1140 in a 159 KB PDF, listed as a schematic though the name contains only the transistor number.

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

Labelled 2SC5256, this 165 KB PDF most likely contains the datasheet for that JIS-coded NPN transistor; an FT-suffixed variant document also exists.

Specification for the 2SC4490 in a 149 KB PDF, readable in any common viewer. The part follows the Japanese JIS scheme where 2SC marks an NPN bipolar transistor; no…

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.

Listed as a schematic, this 102 KB PDF is named after 2SC5042, which under Japanese JIS rules designates an NPN transistor, so a component datasheet is the likely…

Part number 2SC5029 names this 212 KB PDF, filed as a schematic. Japanese JIS numbering assigns the 2SC prefix to NPN bipolar transistors, so the content should be a…
