Covering the 2sk2580, this 34.5 KB PDF is labelled a schematic yet identifies only a semiconductor part, pointing to a short datasheet.

Covering the 2SK2459N, this 138 KB PDF sits in the schematic section but by its name is a transistor datasheet; 2SK is the Japanese JIS prefix for N-channel field-effect…

A PDF of about 88 KB for the 2SK2154, filed under schematics but most likely a component datasheet, since the name is just the part number.

Reference sheet for the 2SK2046, supplied as an 88.4 KB PDF. The 2SK designation belongs to the Japanese registration scheme for N-channel field-effect transistors…

Reference PDF covering the 2SK1842, a part number in the JIS 2SK series used for N-channel field-effect transistors.

Datasheet-style PDF for the 2SK1117, with the name noting NTE2379 as its equivalent, meaning the NTE replacement line lists that part as a cross-reference.

Component sheet for the 2SK1069, an N-channel FET from the Japanese 2SK numbering range, stored as a 98.7 KB PDF.

A PDF filed under schematics but named after the 2SK404, a part number in the Japanese JIS semiconductor scheme, where the 2SK prefix marks an N-channel field-effect…

A 161 KB PDF carrying only the part number 2SC4650, a JIS-registered NPN transistor. Nothing in the name links it to a specific device, so treat it as a component…

Reference sheet for the 2SC4627, a JIS-numbered NPN transistor, supplied as a 61 KB PDF.

Catalogued as a schematic, this 184 KB PDF is named only after the part number 2SC5175, so it is most likely the manufacturer datasheet for that discrete transistor.

Datasheet-style PDF of 88.2 KB for the semiconductor 2SC4475, catalogued in the schematic section.

Named only after the part 2SC4363, this 88 KB PDF is catalogued as a schematic but is most likely the manufacturer datasheet for that transistor.

A 51.7 KB PDF for the 2SC4208, with an _E suffix in the name whose meaning is not stated; it could mark an edition or language version, but that is unconfirmed.

The name of this 156 KB PDF is just the part number 2SC4134, so despite its schematic label it should be the datasheet for that transistor.

For the 2SC5534 transistor, this 44.8 KB PDF sits in the schematic category but, going by the JIS 2SC code for NPN bipolar devices, is the part datasheet.

Catalogued as a schematic, this 45.8 KB PDF is named after the 2SC5503, a part number in the Japanese 2SC series used for NPN bipolar transistors.

Component reference in PDF form for the 2SC4002, 77.6 KB, filed in the schematic category.

Filed under schematics, the 2SC3993 PDF (107 KB) is far more likely a component datasheet, since the name is simply a JIS transistor part number.

A 52.6 KB PDF for the 2SC3933, labelled with an _E suffix and catalogued as a schematic.

Compact 30.5 KB PDF for the 2SC3923, named by part number alone and sorted into schematics.

Brief datasheet-type PDF for the 2SC3920 at 30.5 KB, indexed under schematics. The file name contains only the part number.

The 2SC5416 base part is described in this 45.8 KB PDF, indexed as a schematic, with an LS variant held in a separate file.

Part-number document for the 2SC3917, delivered as a 30.8 KB PDF. The 2SC prefix follows the JIS system for NPN bipolar transistors, so the content should be a datasheet…

A small PDF filed as a schematic, though the name is simply the part number 2SC3468, which follows the Japanese JIS semiconductor scheme where the 2SC prefix marks an…

Part number 2SC3401 is the only information in the name of this 87.3 KB PDF, so no device or board is identified.

Covering the 2SC5353, this 208 KB PDF sits in the schematic category but, judging by the name, documents a single transistor.

A 97.4 KB PDF for the 2SC3151, an NPN bipolar transistor according to its JIS 2SC designation.

The 2SC3116 NPN transistor is described in this 47.6 KB PDF, placed in the schematic category.

Catalogued as a schematic, this 190 KB PDF is named after the 2SC2999, a part number in the Japanese JIS scheme where the 2SC prefix marks an NPN bipolar transistor.

A 508 KB PDF filed under schematics, named only with the JIS part number 2SC2996. The 2SC prefix identifies an NPN bipolar transistor, so the document is probably a…

Named 2SC2859, this 192 KB PDF is indexed among schematics but probably holds the datasheet of a JIS-numbered NPN bipolar transistor, as the 2SC prefix suggests.

Datasheet-style PDF of 170 KB for the 2SC1627A, the A-suffixed variant of a JIS-numbered NPN bipolar transistor, indexed as a schematic.
