The 2SC2347 is the subject of this 292 KB PDF, filed as a schematic but most likely a datasheet for the NPN transistor.

The 2SK2094 N-channel FET is the subject of this 127 KB PDF, which is catalogued as a schematic though the bare part-number name points to a datasheet.

The 2SK1420, an N-channel FET according to the Japanese JIS 2SK prefix, is the subject of this 103 KB PDF.

An 81.5 KB PDF indexed as a schematic and named 63cpq100. No laptop, board number or revision is mentioned, so its subject must be confirmed by opening it.

Part 2SK2399 is the subject of this 423 KB PDF, catalogued as a schematic but in all likelihood a datasheet, since under Japanese JIS numbering 2SK stands for an…

The 2SA940A is the subject of this 165 KB PDF, filed as a schematic though the name is a JIS transistor number.

The 2SA1765 PNP bipolar transistor, identified by its JIS 2SA prefix, is the subject of this 99.6 KB PDF catalogued as a schematic.

Michaels International diode equivalents guide, a large 8.42 MB PDF catalogued here as a schematic but actually a cross-reference book.

The 2SD1061 is the subject of this 102 KB PDF, placed in the schematic section though it reads as a part datasheet.

The 2sc4725 is the subject of this 56.8 KB PDF, categorised as a schematic. Since 2SC is the JIS designation for NPN bipolar transistors, the document is most probably…
