PDF of about 295 KB for the 2SK1827. In JIS part numbering, 2SK stands for an N-channel FET, so the content should be a datasheet rather than a board-level drawing.

Document for the 2SK1806 in PDF format, 136 KB, catalogued as a schematic. The 2SK code marks an N-channel FET under JIS naming, so the contents are likely a component…

An 88.5 KB PDF on the 2SK1738 transistor. In the JIS system, 2SK designates an N-channel FET, so this file is most likely the datasheet rather than a circuit schematic.

Reference PDF for the 2SK1457, filed under schematics and 122 KB in size. The file name carries only the part number.

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

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

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…

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

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

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…

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…

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.

Datasheet for the 2SD882 NPN transistor in a 165 KB PDF; the file name does not state which manufacturer issued it, unlike the UTC versions in the same set.

A 177 KB PDF describing the 2SC4689, placed in the schematic category of the catalogue.

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

Catalogued as a schematic, this 41.7 KB PDF bears the part number 2SC5611 and should be the datasheet for that NPN bipolar transistor.

Filed as a schematic, this 464 KB PDF carries just the name 2SC4322 and should be read as a transistor datasheet.

Datasheet-style PDF for the 2SC4271 transistor, catalogued here under schematics and weighing 78.2 KB. The name gives only the part number, with no maker or revision.

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

Datasheet PDF for the 2SC5575, 52.0 KB, placed in the schematic section of the index. The file name contains only the part number.

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

Catalogued as a schematic, this 89.4 KB PDF bears the part number 2SC4133, a JIS designation for an NPN bipolar transistor, so its content is most likely the device…

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.

A 463 KB PDF for the 2SC380TM, an NPN transistor numbered under the JIS 2SC scheme; TM is part of the name but its meaning is not explained.

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…

Component data for the 2SC5531 NPN bipolar transistor, supplied as a 51.5 KB PDF and catalogued under schematics.

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 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…

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…

At only 24.2 KB, the 2SC3989 PDF is a compact document, probably a short datasheet or summary page for this JIS-numbered NPN bipolar transistor despite being indexed as…

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

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