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

The 2SK2995 is the subject of this 418 KB PDF, filed among schematics but by its name a transistor datasheet.

Datasheet in PDF form for the 2SK2962, 385 KB in size and catalogued as a schematic. The 2SK series denotes N-channel FETs registered under the Japanese JIS scheme, so…

Datasheet-style PDF, 137 KB, covering the 2SK2550 transistor even though the catalogue lists it as a schematic.

Lowercase-named PDF of 136 KB covering the 2SK2503, catalogued as a schematic though it relates to a single transistor.

A 134 KB PDF identified solely as 2SK2219, placed in the schematic category but most likely a transistor datasheet.

This 96.1 KB PDF is named 2SK2161 and placed with schematics, but a part-number title like this usually signals a single-device datasheet.

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…

Covering the 2SK1828, this 319 KB PDF is catalogued as a schematic but is most likely the component datasheet.

A 104 KB PDF dedicated to the 2SK1424, an N-channel field-effect transistor going by its JIS 2SK prefix.

Here the 2SK1422 transistor is documented in a 103 KB PDF filed under schematics, though content is most likely a datasheet rather than a board diagram.

A small 98.7 KB PDF about the 2SK1416, catalogued under schematics but most likely a component datasheet.

Datasheet in PDF format for the 2SK932, around 91.5 KB. The 2SK prefix denotes an N-channel FET registered under JIS numbering, and the file name contains no extra…

Datasheet for the 2SK771 N-channel FET, supplied as a 79.5 KB PDF. Only the part number appears in the name.

PDF of roughly 332 KB dedicated to the 2SJ610 part number and catalogued as a schematic.

The 2SJ609 is documented in this 30.0 KB PDF, listed under schematics but named in the manner of a component datasheet.

Reference PDF, 110 KB, for the 2SJ383 transistor, catalogued under schematics but by name a datasheet.

PDF file of about 148 KB describing the 2SJ315, listed in the schematic section. No board or brand is mentioned, only the part number.

PDF of 245 KB titled 2SJ200, which by Japanese JIS convention is a P-channel field-effect transistor; the contents are probably the datasheet rather than a circuit…

Under the schematic category, this 99.0 KB PDF titled 2SJ187 should be the datasheet for a P-channel FET, as the JIS 2SJ prefix indicates.

A 94.8 KB PDF documenting the 2SD895, indexed as a schematic though the name names a single transistor.

Datasheet-type PDF of 47.9 KB for the 2SD894, placed under schematics. The name holds only the part number, which follows JIS conventions where 2SD indicates an NPN…

Part documentation for the 2SC4727 in a 108 KB PDF. Catalogued under schematics, the file is named for a component whose 2SC prefix marks an NPN bipolar transistor in…

The 2SC5230 is described in this 129 KB PDF, indexed as a schematic even though its name is a discrete part number.

Reference sheet for transistor 2SC4474, supplied as a 109 KB PDF and listed among schematics.

At 466 KB, this PDF for the 2SC4325 sits under schematics, yet the name is a bare transistor part number, so expect a component datasheet.

PDF of 49.9 KB titled 2SC5568, indexed among schematics. The file name offers nothing besides the part number; the 2SC prefix follows JIS/JEITA naming for NPN…

Indexed as a schematic, this 321 KB PDF carries only the part number 2SC5748. Under JIS/JEITA naming, a 2SC code belongs to an NPN bipolar transistor, so the document is…

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

Indexed under schematics, the 197 KB PDF for the 2SC5460 is most probably a full datasheet for this NPN transistor from the Japanese 2SC series.
