The 2SK1747 is the subject of this 184 KB PDF. Japanese JIS designation 2SK means an N-channel field-effect transistor, so the file is probably the manufacturer…

Datasheet PDF for the 2SK1472 N-channel field-effect transistor, inferred from the Japanese 2SK designation, though the catalogue files it under schematics.

Labelled 2SK1451, this 111 KB PDF sits in the schematic section but by name looks like a transistor data sheet. The JIS 2SK code belongs to N-channel FETs.

Component datasheet in PDF, 86.7 KB, for the 2SK546, listed among schematics. Following JIS numbering, 2SK parts are N-channel FETs, so the document covers a single…

A 31.0 KB PDF for the 2SJ597, stored in the schematic category although it is named like a single-part datasheet.

Datasheet for the 2SJ412 P-channel field-effect transistor, provided as a 328 KB PDF; the larger size suggests detailed curves and package drawings.

Datasheet PDF of 107 KB for the 2SJ381, indexed as a schematic. The prefix 2SJ comes from the Japanese JIS discrete semiconductor scheme and denotes a P-channel FET.

At 414 KB this is one of the larger PDFs in the 2SJ series, covering the 2SJ334. Only the part number appears in the name.

The 2SJ287 is covered in this 96.7 KB PDF. Only the part number is present in the name, so no equipment details can be given.

Covering the 2SD1246, this 85.2 KB PDF is filed among schematics but its name is simply a JIS transistor number.

A 103 KB PDF covering the 2SD1063, filed as a schematic although the name points to a single semiconductor rather than a device.

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…

Compact UTC datasheet, around 14 KB, for the 2SD880 NPN transistor from Unisonic Technologies.

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

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…

A 155 KB PDF for the 2SC5245 transistor, catalogued as a schematic but by its name almost certainly a component datasheet.

At 280 KB, this PDF for the 2SC5233 is one of the larger documents in the series and is indexed as a schematic, though the name identifies a single part.

A 271 KB PDF for the 2SC5232, listed as a schematic yet named like a single-component datasheet. JIS numbering gives the 2SC prefix to NPN bipolar transistors.

Datasheet-style document for the 2SC4617, marked revision 0 in the file name and stored as a 128 KB PDF under the schematic category.

A 136 KB PDF for the 2SC4616, listed among schematics though the name only carries a component part number, implying a transistor datasheet.

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.

A 172 KB PDF labelled 2SC5174, filed under schematics, though the name points to a component datasheet rather than a board drawing.

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.

An 84.4 KB PDF for the 2SC4547, sorted into schematics but named like a single-component datasheet.

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

The 2SC5122 is named in this 171 KB PDF, which the index lists under schematics even though the title is only a component number, suggesting a datasheet.

Transistor datasheet in PDF for the 2SC4247, 302 KB, indexed with schematics rather than board diagrams. Only the part number is provided in the name.

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.

PDF of 49.6 KB named 2SC5565, catalogued with the schematics although it refers to a single semiconductor.

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…

A 103 KB PDF named only after the part 2SC3992, indexed as a schematic but in practice almost certainly a transistor datasheet.

Datasheet for the 2SC3939 transistor in a 51.2 KB PDF, catalogued as a schematic; the _E ending likely marks an English-language release, though the name does not…

The 2SC5404 is covered by this 319 KB PDF, which the index files as a schematic. The name carries only the transistor number.

Reference PDF for the 2SC4869, 126 KB, sorted into the schematic category. Nothing else is given in the name.
