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.

A 42.8 KB PDF for the 2SC5639, placed under schematics although its name is a bare part number pointing to a transistor datasheet.

Bearing only the part number 2SC4393, this 319 KB PDF is indexed as a schematic yet is most likely the transistor datasheet.

Smallest of the batch at 30.8 KB, the PDF named 2SC5607 is presumably a concise datasheet for that NPN transistor despite being labelled a schematic.

A 475 KB PDF referencing the 2SC5092 transistor type; the 2SC prefix denotes an NPN bipolar device under the Japanese JIS numbering system.

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

Datasheet PDF for the 2SC5537 transistor, 32.5 KB, catalogued with schematics. In the JIS scheme 2SC denotes an NPN bipolar part, so this is component data rather than a…

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…

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

PDF documentation for the 2SC3929 transistor, 54.1 KB, suffixed _E and filed under 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.

Named simply 2SC4984, this 48.8 KB PDF is catalogued as a schematic yet points to a discrete semiconductor.

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.

A 53.1 KB PDF referencing the 2SC3902, an NPN bipolar transistor under JIS numbering, where 2SC marks that device class.

2SC3789 is the sole identifier on this 157 KB PDF, placed in the schematic section of the index.

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.

Datasheet PDF of 172 KB carrying the part number 2SC5358, listed under schematics in the index.

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

Component documentation for the 2SC3183 transistor, supplied as a 106 KB PDF and listed under schematics.

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

Component reference for the 2SC3124, a 294 KB PDF indexed as a schematic. The JIS 2SC designation identifies it as an NPN bipolar transistor, normally marked C3124.

Reference document for the 2SC3112 transistor, supplied as a 257 KB PDF and filed under schematics. The name holds only the part number.

The 2SC3099 is the only detail this 318 KB PDF name gives, and the file is indexed as a schematic, although it is probably a datasheet.

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.

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.

Indexed as a schematic, this 187 KB PDF is named after the 2SC2880, which the JIS 2SC prefix identifies as an NPN bipolar transistor.

A 186 KB PDF identified by the part number 2SC2873 and classed as a schematic. Under the JIS standard the 2SC prefix means an NPN bipolar transistor, so this is most…

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

Short PDF of 50.8 KB for the 2SC1509, with an _E suffix in the file name, listed in the schematic section.
