Only 29.3 KB, this PDF named 2SK2380 sits under schematics but is most likely a brief datasheet for an N-channel FET, per the Japanese JIS 2SK prefix.

Short PDF of about 34 KB tied to the 2SK2128 part number. It is catalogued as a schematic, but with nothing besides the part number in the name it is presumably a…

Catalogued as a schematic, this 31.8 KB PDF is named 2SK1443LS, pointing to a suffixed variant of the 2SK1443. The name does not clarify the LS suffix.

A 105 KB PDF for component 2SK1432, categorised as a schematic though the name identifies only a single transistor.

PDF sheet for the 2SK1233 MOSFET, size 46.1 KB, part of the Japanese 2SK series of N-channel field-effect transistors.

Short 34.3 KB PDF for the 2SK1228 N-channel field-effect transistor, catalogued among schematics. The 2SK prefix identifies a JIS-registered Japanese N-channel FET.

A 164 KB PDF dedicated to the 2SD1221, recorded as a schematic in the catalogue. Japanese JIS numbering uses the 2SD prefix for NPN bipolar transistors in low-frequency…

Brief 41.5 KB PDF on the 2SD1211 with an _E suffix, entered in the schematic category. Under JIS conventions the 2SD prefix stands for an NPN bipolar transistor for…

PDF datasheet material for the 2SD1194 transistor, about 138 KB, catalogued here under schematics.

Datasheet PDF of 42.5 KB for the 2SD1119, with an _E suffix following the number whose meaning the name does not give. The index files it as a schematic.

PDF datasheet, 89.5 KB, for the 2SC4633 transistor, though the index files it under schematics.

Datasheet PDF for the 2SC5229, 135 KB, kept in the schematic category of the index. Japanese JIS part numbering assigns 2SC to NPN bipolar transistors, which identifies…

PDF of 171 KB for the 2SC5199, the same size as several neighbouring 2SC519x entries, which hints at a shared document format or a combined sheet.

Small 41 KB PDF for the 2SC5190, with an _E suffix that may denote an English-language edition, though the name does not state this.

At just 39.2 KB, the PDF named 2SC4291 is a compact document filed as a schematic, though the name suggests a brief transistor datasheet.

Short 88.9 KB PDF carrying the transistor number 2SC4217, filed among schematics. JEITA assigns the 2SC prefix to NPN bipolar transistors, so this should be a datasheet…

Component sheet for the 2SC4209 in PDF format, 187 KB. The original name contains just the part number, so details like package, maker or revision are absent.

Another 469 KB PDF from the 2SC48xx range, this one labelled 2SC4842. The 2SC prefix in JIS semiconductor numbering denotes an NPN bipolar transistor, so despite the…

Specification PDF for the 2SC4924 NPN transistor, roughly 79 KB. No manufacturer, package or application appears in the name, only the JIS-style part number.

Component documentation for the 2SC3669 in PDF format, 192 KB in size. The 2SC prefix in Japanese JIS numbering indicates an NPN bipolar transistor, and the bare…

A 44 KB PDF for the 2SB1473, with the _E suffix probably indicating an English version, catalogued as a schematic but by its name a component datasheet.

Reference sheet for the 2SA1624 transistor, saved as a 128 KB PDF and indexed in the schematic category.

PDF file of 231 KB for the 2SA1586, catalogued as a schematic but named after one discrete semiconductor.

PDF for the 2SA1487, 38.8 KB, carrying an _E suffix that the name does not explain, possibly an edition or language marker.

Compact 45.3 KB PDF for the 2SA1207, listed as a schematic, though the name offers only the part number, which suggests a datasheet.

Filed as a schematic, this 138 KB PDF bears only the 2SA1204 part number, so it most likely contains the manufacturer datasheet.

Reference sheet in PDF form (150 KB) for the registered semiconductor number 2N6804, catalogued under schematics.

Datasheet-type PDF, 244 KB, for the JEDEC part 2N6036, filed in the schematic category of the index. The name provides only the part number, with no maker or revision.
