The 2SK1456 is the only information in the name of this 124 KB PDF, which is indexed as a schematic.

Data for the 2SJ608 in a lightweight 27.9 KB PDF, indexed as a schematic. Under the Japanese JIS scheme the 2SJ prefix denotes a P-channel FET, so this is likely a…

A 29.4 KB PDF for the 2SJ569LS, catalogued as a schematic though it is named in the style of a component datasheet.

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…

Nothing beyond the code 2SJ272 is given in the name of this 92.3 KB PDF. Japanese JIS numbering assigns the 2SJ prefix to P-channel field-effect transistors, so the…

PDF reference for the 2SC4257 transistor, 81.6 KB, filed under schematics although it is a part document rather than a board drawing.

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

PDF reference for the 2SC4881, 183 KB in size, categorised under schematics. Only the part code is given, which in JIS naming indicates an NPN bipolar transistor; maker…

Reference PDF, 99.3 KB, for the 2SC3994, listed in the schematic category but named like a transistor datasheet.

Datasheet-style PDF for the 2SC3988, 114 KB, filed in the schematic category though the name is a plain JIS transistor number.

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.

File name 2SC3786 offers nothing beyond a transistor type number, and the 81.5 KB PDF is placed in the schematic category.

Indexed as a schematic, this 95.8 KB PDF carries only the designation 2SC4821. In the JIS system the 2SC prefix denotes an NPN transistor, so the content is most likely…

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.

Compact 102 KB PDF for the 2SC3090 transistor, indexed under schematics. The name carries no detail beyond the part code.

Named for the 2SC2995, this 510 KB PDF is listed as a schematic but most likely holds the datasheet for a JIS-numbered NPN transistor, as the 2SC prefix indicates.

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…
