The 34.0 KB PDF named 2SK3557 is indexed as a schematic, but its name is a JIS component number, so it is almost certainly a datasheet.

For the 2SK2744 this 177 KB PDF provides component-level reference material, although the index lists it among schematics.

Part reference for the 2SK2607, an N-channel FET according to the 2SK prefix of the JIS numbering convention.

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

The 2SK2545 is the subject of this 415 KB PDF, catalogued as a schematic but by its name a discrete transistor document.

Component documentation in PDF format, 32.4 KB, for the 2SK2326. The 2SK prefix follows the JIS registration scheme and signifies an N-channel FET, so despite the…

Datasheet in a 33.2 KB PDF for the 2SK1967, a Japanese-registered N-channel field-effect transistor indicated by the 2SK prefix.

PDF, 121 KB, for the 2SK1474 transistor. Japanese 2SK numbering denotes an N-channel field-effect device, so although the index category is schematic, the content is…

The 2SK1375 N-channel field-effect transistor is covered by this 150 KB PDF, filed under schematics in the catalogue.

Small 43.1 KB PDF for the 2SJ400, likely a short datasheet despite being indexed as a schematic.

PDF document for the 2SJ346, filed in the index as a schematic but named after a discrete semiconductor part.

PDF datasheet of about 56 KB for the 2SD661 transistor, with an _E suffix that probably indicates an English edition.

The 2SC4690 is the subject of this 175 KB PDF, which the index files as a schematic even though the name points to a single transistor document.

Base-version document for the 2SC4738, a 236 KB PDF placed in the schematic category. Following the JIS scheme, the 2SC prefix denotes an NPN bipolar transistor; F and…

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…

Named after the transistor type 2SC4646, this 148 KB PDF most likely contains the part datasheet. No board, model or revision is mentioned.

PDF document, 39.0 KB, for a part named 2SC4627J, with an extra _E tag in the name whose meaning is not stated.

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

The 2SC5144 is the only detail this 206 KB PDF name carries; despite the schematic label it is presumably the device datasheet for that transistor.

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.

Compact 43.3 KB PDF covering the 2SC5551, a JIS-coded NPN bipolar transistor, even though the catalogue type says schematic.

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.

A 39.3 KB PDF for the 2SC5490 component, which belongs to the 2SC range of NPN bipolar transistors under Japanese JIS numbering.

A 45.1 KB PDF listed under schematics for the 2SC5448, a part number that under the Japanese JIS scheme identifies an NPN bipolar transistor.

Here is a 49.4 KB PDF for part 2SC4067, placed under schematics but named like a manufacturer datasheet.

Datasheet PDF, 81.8 KB, for the 2SC3997 transistor, placed in the schematic listing. JIS numbering uses 2SC for NPN bipolar transistors; nothing else, such as maker or…

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.

Single-part reference for the 2SC4864 in a 118 KB PDF, catalogued as a schematic. Apart from the part number, the name gives no information.

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

An 84.6 KB PDF for the 2SC3071, filed as a schematic. The name supplies nothing beyond the part number, so this is probably a compact datasheet.

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.
