PDF of 119 KB for the 2SD1207, categorised as a schematic though its name is a JIS transistor number.

Short PDF of 43.2 KB for the 2SD1149, with an _E suffix after the part number that the name leaves unexplained. It is indexed as a schematic but reads as a datasheet.

Only 21.9 KB, this PDF relates to the 2SD1048 and is indexed among schematics, though the name identifies a discrete part.

PDF of 30.5 KB for the 2SD1047P, a variant carrying a P suffix that the name does not explain; it may denote a package or grade, so compare it with the plain 2SD1047…

Component datasheet for the 2SD638 NPN transistor, roughly 45 KB in PDF format and catalogued with schematics.

The 2SC5263 is covered by this 103 KB PDF, listed among schematics in the index. Following Japanese JIS numbering, 2SC marks an NPN bipolar transistor, and no variant…

Indexed as a schematic, this 59 KB PDF carries the name 2SC4655 with an E suffix, which plausibly denotes an English-language version.

A small 30.6 KB PDF for the 2SC4637LS. The LS suffix appears to denote a particular package or lead variant of the 2SC4637 NPN transistor, so check the outline drawing…

PDF of about 99 KB for the 2SC4770, filed under schematics though the name points to a transistor datasheet rather than a board diagram.

Covering the 2SC4612, this 155 KB PDF is indexed as a schematic but is in practice a transistor datasheet, as only the part number appears in the name.

2SC5154 is the only detail in this 198 KB PDF name, and that JIS designation points to an NPN bipolar transistor of the high-frequency group, so treat the file as a…

The 121 KB PDF labelled 2SC4598 sits in the schematic section, yet the name is a discrete component number, so expect a datasheet.

The 86.7 KB PDF named 2SC4572 is filed as a schematic yet carries a transistor part number, so expect a component datasheet rather than a circuit diagram.

Part-number named PDF, 205 KB, for the 2SC5142 transistor; though catalogued as a schematic, it is likely the manufacturer datasheet.

A 341 KB PDF named for the 2SC5612, filed under schematics while most likely being the full component datasheet. JIS numbering assigns 2SC to NPN bipolar transistors.

The 2SC4253 transistor is documented in this 303 KB PDF, indexed among schematics. Only the part number is given in the name; maker and revision are not stated.

Small 92.6 KB PDF bearing only the part number 2SC4219. Although the catalogue lists it as a schematic, the 2SC prefix, the JEITA code for an NPN bipolar transistor…

Datasheet PDF, 52.4 KB, for the 2SC5574, with the type number written in lowercase in the original name.

PDF document of 331 KB named after the 2SC4116 part number, filed in the index under schematics.

Catalogued as a schematic, this 349 KB PDF bears the name 2SC5570, a JIS/JEITA designation for an NPN bipolar transistor.

The 2SC5088 transistor is the subject of this 481 KB PDF, catalogued as a schematic though it most likely holds the component datasheet.

Documentation for the 2SC5548 NPN bipolar transistor, a 231 KB PDF catalogued under schematics, with a separate 2SC5548A variant also present in the collection.

Concerning the 2SC5452, this 42.4 KB PDF is listed as a schematic but, judging by size and part number, is a component datasheet for an NPN transistor in the Japanese…

Reference sheet for the 2SC3990 transistor, stored as a 104 KB PDF and catalogued under schematics.
