The 2SK3121 is covered by this 126 KB PDF, which the index lists as a schematic although it serves as a part datasheet.

A 368 KB PDF covering the 2SK2998, a part whose 2SK prefix follows the Japanese JIS scheme for N-channel FETs.

A compact 136 KB PDF for the 2SK2989, listed as a schematic yet by name a discrete transistor document. Under the JIS convention 2SK marks an N-channel FET.

Part sheet for the 2SK2698, delivered as a 413 KB PDF. Following JIS naming, 2SK parts are N-channel FETs, and the file size points to a complete datasheet with graphs…

Listed among schematics, this 97.3 KB PDF is named for the 2SK1887. Japanese JIS designations starting 2SK belong to N-channel field-effect transistors, so expect…

PDF of 101 KB for the 2SK1849 transistor, listed with schematics. In JIS numbering the 2SK prefix identifies an N-channel FET, so this should be the device datasheet…

PDF of 56.2 KB named 2SD1391, a JIS designation for an NPN low-frequency bipolar transistor, and presumably its datasheet although indexed under schematics.

Listed under schematics, this 110 KB PDF is named for the 2SD1347, an NPN bipolar transistor in the Japanese JIS 2SD series, and is probably its datasheet.

The 2SC4527 data sheet, a 310 KB PDF filed under schematics but in practice a component specification.

Short 40.3 KB PDF describing the 2SC5578 transistor. No manufacturer, package or version appears in the file name.

Compact 29.9 KB PDF for the 2SC5775 transistor, filed under schematics despite the name being a bare part number.

Datasheet-style PDF, 469 KB, for the 2SC5091 NPN transistor, listed in the schematic section of the index.

A brief 37.5 KB PDF identified only by the part number 2SC5710. JIS numbering assigns 2SC to NPN bipolar transistors, so this is likely a concise datasheet.

Carrying only the part number 2SC5030, this 212 KB PDF is categorised as a schematic, but the JIS 2SC prefix identifies an NPN transistor and the file is most likely its…

A 79.7 KB PDF for the 2SC3950 transistor, placed in the schematic category though the part-number name indicates a component datasheet.

A 40.9 KB PDF titled 2SC3937 with the _E suffix often used for English versions of Japanese datasheets, listed here under schematics.

PDF of about 138 KB for the 2SC3771, a JIS-numbered NPN transistor. Although categorised as a schematic, the single part number in the name indicates a component…

Datasheet-style PDF, 217 KB, for the 2SC3668 transistor; the name supplies no other details.

Only the code 2SC5347 identifies this 115 KB PDF, so no model, board or revision is known.

PDF of 137 KB identified only by the part number 2SC2782, filed with schematics but almost certainly a transistor datasheet.

A 349 KB PDF named for the 2SC2670 transistor and catalogued as a schematic, most likely containing the device datasheet. JIS 2SC numbering identifies NPN bipolar parts.

Reference PDF of 136 KB for the 2SA1406 transistor, catalogued among schematics. The 2SA prefix, by JIS convention, marks a PNP device in the high-frequency category.

Compact 40.8 KB PDF for the 2SA1257, indexed as a schematic though its name carries only a part number.

Filed under schematics, a 164 KB PDF named 2N6387 with an RE suffix that the name does not explain.

A 121 KB PDF for the 2N6027, filed as a schematic but most likely the device datasheet. The name gives no manufacturer, package or revision.
