Combined datasheet PDF of 210 KB covering the 4N25 to 4N28 and 4N35 to 4N37 optocouplers, although indexed as a schematic.

Small 21 KB PDF covering the 4N39 optocoupler, catalogued as a schematic. The name states only the part number, so the content is most likely a brief datasheet with…

Listed as a schematic, the 307 KB PDF titled 2SK118 is by name a component datasheet for a Japanese JIS-numbered device.

A 40.8 KB PDF on the 2SK2012, an N-channel FET according to the JIS 2SK naming convention.

The 2SK1266 N-channel field-effect transistor is documented in this 33.9 KB PDF, indexed as a schematic.

A 110 KB PDF labelled 2SJ440 and listed under schematics. The 2SJ prefix is the Japanese JIS code for P-channel field-effect transistors, so the content is likely a…

A compact 27.8 KB PDF named after 2SJ164, a JIS designation identifying a P-channel FET.

A small 49.5 KB PDF for the 2SC4767 part, filed as a schematic; the trailing _E in the name is not explained, so check the document to see what it denotes.

A 274 KB PDF named after the part number 2SC4244, filed under schematics but most likely a component datasheet.
