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.

Documentation for the 2SJ378 P-channel FET in a 418 KB PDF, listed as a schematic though really a datasheet.

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

Reference sheet for the 2SC5298 in a 95.7 KB PDF. Parts with the 2SC prefix are NPN bipolar transistors under the Japanese JIS numbering system, so the content is likely…

A 195 KB PDF labelled with the transistor type 2SC4210. No device, board or manufacturer is named; the 2SC prefix simply tells us, through the Japanese JEITA system…

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

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

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

A 96.0 KB PDF for the 2SC3687 transistor, placed in the schematic category of the index. According to the Japanese JIS system, the 2SC prefix means NPN bipolar.

Named for the 2SC2555, this 186 KB PDF is filed under schematics but is most likely the component's datasheet.

For the 2SA1356, this 177 KB PDF carries just the part number, so it is most probably the device datasheet rather than a full circuit diagram.

A 163 KB PDF titled with the part number 2SA1256, filed in the schematic category. The 2SA designation, part of the JIS numbering system, identifies a PNP transistor…

Covering the 2SA1242, this 212 KB PDF carries only the part number in its name, so it is best treated as the component datasheet despite the schematic label.

Catalogued as a schematic, this 130 KB PDF is titled with the part number 2N6800 and nothing else. No equipment model or board revision is given.

The 2N6274 is covered by this 169 KB PDF, indexed as a schematic though it is presumably a manufacturer datasheet for the component.

Filed under schematics, this 65.3 KB PDF is named only for the 2N5191 part number, so it is almost certainly a component datasheet rather than a board drawing.

PDF reference of 45.2 KB for the 1T363 transistor, filed in the schematic section. The designation follows the old Soviet system, where 1T stands for a germanium…

Laptop mainboard schematic for the Quanta TE1 design, provided as a 720 KB PDF with no revision or retail model in its name.

Datasheet PDF, 60 KB, for the 2SD1650, with the name given in lowercase and filed under schematics.

Part number 2SD1424 with an unexplained _E suffix names this 41.4 KB PDF, indexed among schematics but most likely a datasheet for the transistor.

Reference sheet for the 3SK180 semiconductor in PDF form, roughly 173 KB, catalogued as a schematic.

For the 2SK3411 transistor, this 32.0 KB PDF provides the component reference, even though the index files it as a schematic.
