At 466 KB, this PDF for the 2SC4325 sits under schematics, yet the name is a bare transistor part number, so expect a component datasheet.

Part 2SC5095 gives this 296 KB PDF its name, and that is the only detail available: no board, revision or manufacturer is stated.

PDF of 49.9 KB titled 2SC5568, indexed among schematics. The file name offers nothing besides the part number; the 2SC prefix follows JIS/JEITA naming for NPN…

The 2SC3894 NPN bipolar transistor is covered by this 84.5 KB PDF, labelled a schematic but named only by a JIS part number, where 2SC denotes NPN devices, so it is most…

Reference sheet in PDF form, about 123 KB, for the 2SC5374 NPN transistor in the Japanese 2SC numbering series.

The bare part number 2SC3419 names this 176 KB PDF, which the index lists as a schematic.

The 2SC5317 transistor is the subject of this 122 KB PDF, which the index lists as a schematic though the name matches a datasheet.

Datasheet PDF, 170 KB, for the semiconductor numbered 2SC2705, placed in the schematic listing. Under JIS naming, the 2SC prefix marks an NPN transistor.

A 349 KB PDF named for the 2SC2670 transistor and catalogued as a schematic, most likely containing the device datasheet. JIS 2SC numbering identifies NPN bipolar parts.

Datasheet-type PDF of 215 KB for the 2SC2655, listed as a schematic. The JIS system uses 2SC for NPN bipolar transistors.

Compact 39.7 KB PDF on the 2SB1370, indexed as a schematic though it documents one discrete device.

A 90.4 KB PDF describing the 2SA1423, identified only by part number. By Japanese JIS convention the 2SA prefix marks a PNP transistor.

Reference PDF covering the 2SA2097 transistor, 150 KB in size and filed as a schematic though it is component data.

Reference sheet in PDF form for the 2SA1969, a part number that under Japanese JIS rules denotes a PNP bipolar transistor.

PDF data for the 2SA1838, sized 87.4 KB and stored in the schematic category of the index.

Reference document for the 2N7002MTF, a 205 KB PDF stored with schematics. The base number 2N7002 is a well-known small-signal N-channel MOSFET, and the MTF letters are…

Small 64.5 KB PDF named 2N6764, placed in the schematic category. Only the JEDEC semiconductor code is given, with no model, brand or board details.

PDF datasheet, 48.1 KB, for the part named 1T3797, indexed among schematics. The 1T prefix follows the Soviet designation pattern used for germanium transistors, though…

A 109 KB PDF filed under schematics, named only 60HQ080. The name gives no manufacturer, product or board number, so the content has to be confirmed by opening it in a…

Named 60EPU02, this 147 KB PDF sits in the schematic category. It carries no brand, model or revision details.

At 207 KB, this schematic-category PDF named 60EPF10 is somewhat larger than its sibling files, but its name still gives no manufacturer, product or revision.
