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…

The 2SK304 appears here as a 79.6 KB PDF. The file name carries nothing beyond the part number, which in the Japanese JIS system indicates an N-channel FET.

A 32.0 KB PDF for part 2SJ616, placed among schematics but named like an individual transistor datasheet.

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.

Component datasheet in PDF form for the 2SJ284, roughly 81.4 KB. The file name names only this part, with no device, board or revision mentioned.

Indexed as a schematic, the 124 KB PDF named 2SJ193 most probably holds the datasheet for that JIS-numbered P-channel FET.

The 130 KB PDF titled 2SD1348 relates to a JIS-numbered NPN bipolar transistor, the 2SD series covering low-frequency types, and is expected to be a component datasheet…

Covering the 2SD1193, this 135 KB PDF is indexed as a schematic but its name identifies a discrete component, so it is most likely the maker's datasheet.

Datasheet PDF for the 2SD1192 transistor, 133 KB, listed in the schematic section of the index. Its name gives nothing beyond the part 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.

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.

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

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

The 2SC4404 is covered by this 114 KB PDF, placed under schematics in the catalogue. According to Japanese JIS numbering, 2SC parts are NPN bipolar transistors, so the…

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.

Datasheet for the 2SC4214 transistor, supplied as a 279 KB PDF. The file name holds nothing beyond the part number, so the manufacturer, package and target equipment…

Datasheet-type PDF for the 2SC5564, 50.0 KB, placed in the schematic category. No model or board appears in the name; the 2SC prefix indicates an NPN transistor for…

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

PDF of 336 KB covering the 2SC732TM, an NPN bipolar transistor of the Japanese 2SC family; the TM suffix appears in the name but is not explained.

Datasheet-style PDF of 181 KB for the 2SC5819 transistor, listed under schematics in the index.

PDF datasheet, 41.0 KB, for the 2SC5506 NPN bipolar transistor, held in the schematic section.

Filed as a schematic, the 112 KB document 2SC5046 is really labelled with a Japanese NPN transistor part number, which suggests a single-component datasheet.

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