For the 2SK614, a part number from the JIS family of N-channel field-effect transistors, this 32.7 KB PDF is catalogued as a schematic but is most plausibly a short…

Filed under schematics, the 143 KB PDF named 2SJ509 most probably holds the datasheet for a single transistor, since 2SJ in the Japanese JIS scheme designates a…

Compact 42 KB PDF for the 2SJ340, catalogued among schematics although the name is a transistor part number. Nothing else about a device or board is stated.

The 2SJ339 appears in this small PDF of roughly 40.7 KB. The name carries only the part number, with no hint of the equipment it came from.

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…

The 2SD1294 is the only detail this 209 KB PDF name provides; the file is filed as a schematic but corresponds to a transistor part number.

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

Datasheet-style PDF of 44.0 KB for the 2SC4391, filed as a schematic; the trailing _E suffix in the name is not explained and could denote an edition or language…

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

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

Indexed as a schematic, this 296 KB PDF is named only 2SC5094, a JIS-style transistor designation where 2SC stands for an NPN device rated for high-frequency operation.

Compact 125 KB PDF for the 2SC5091FT, an NPN bipolar transistor numbered under the Japanese 2SC scheme, with the FT suffix as part of the name; its exact meaning is not…

Larger than most in this series at 474 KB, this PDF is for the 2SC5084, an NPN bipolar transistor according to the JIS 2SC prefix, catalogued here as a schematic.

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

The 2SC5540 transistor is covered by this 30.9 KB PDF, catalogued as a schematic. By JIS convention the 2SC prefix signifies an NPN bipolar device, so the document is…

Small 46.2 KB PDF for the 2SC5501. Under the Japanese JIS scheme, a 2SC prefix marks an NPN transistor intended for high-frequency use.

Covering the 2SC5028, this 219 KB PDF is filed as a schematic yet is named like a component datasheet.

PDF document of 90.2 KB titled with the part number 2SC3995 and filed as a schematic. The 2SC prefix follows JIS naming for NPN bipolar transistors; the name gives no…

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

Datasheet PDF for the 2SC3931, 60.7 KB, with the _E suffix common to this group of files and listed as a schematic.

The 2SC3922 is the subject of this short 30.5 KB PDF, listed as a schematic with no suffix or revision in its name.

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

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…

Indexed as a schematic, this 195 KB PDF carries just the type number 2SC3803. In JIS semiconductor naming, 2SC stands for an NPN transistor, so the content is most…

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…

Indexed as a schematic, this 108 KB PDF documents the 2SC4891, an NPN transistor by JIS designation.

PDF reference for the 2SC3596, sized at 119 KB and indexed with schematics although it describes a single semiconductor.

Covering the 2SC3547A, this 288 KB PDF is a transistor datasheet indexed in the schematic section.

Small 39.7 KB PDF for the 2SC3526, carrying an _E suffix in its name whose meaning, perhaps a language edition or document revision, cannot be confirmed from the name…

For the 2SC3503, a 158 KB PDF datasheet listed with schematics. Only the part number is given; per the JIS system, a 2SC number belongs to an NPN bipolar transistor…

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