Short datasheet-type PDF of 30.0 KB for the 2sk2588, an N-channel FET according to the JIS 2SK prefix.

PDF document for the 2SK2374 part, filed under schematics but named after a Japanese-registered semiconductor rather than a board.

Part-number-only PDF for the 2SK2323, 23.2 KB, placed in the schematic category of the index.

Copy of documentation for the 2SK2294, 135 KB in PDF, with an _1-5 suffix in its name that is not explained and may indicate a different edition or page selection.

Documentation for the 2SK2036 in a 326 KB PDF. Parts beginning with 2SK are N-channel field-effect transistors under the Japanese JIS numbering, so this file should be…

PDF of 33.4 KB describing the 2SK2016 transistor, an N-channel FET by its JIS 2SK prefix. It is catalogued as a schematic but is best used as a component datasheet.

Datasheet-style PDF for the 2SK1840, sized 87.3 KB. Part numbers beginning with 2SK are registered under the Japanese JIS scheme for N-channel field-effect transistors.

The 2SK1839 is covered in this 84.9 KB PDF, filed under schematics though the name points to a single semiconductor part.

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…

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.

A compact 32 KB PDF named 2SK1447LS, filed as a schematic. It appears to cover a variant of the 2SK1447 carrying an LS suffix, whose meaning the name does not explain.

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

For the 2SK664 transistor, this 34.9 KB PDF is indexed as a schematic but, judging by the JIS 2SK naming used for N-channel field-effect transistors, it is a datasheet…

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.

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…

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…

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.

Specification PDF, roughly 32 KB, for the 2SD667 transistor, listed among schematics but in fact a component datasheet.

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.

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

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

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…

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…

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…

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…

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

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.

A 41.3 KB PDF named 2SC5018 with an additional _E suffix that the name does not explain.

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.
