A 111 KB PDF for the 2SD2281, which under the Japanese JIS system is an NPN transistor from the low-frequency 2SD series.

A 166 KB PDF for the 2SD1904 transistor, listed here as a schematic but by its name almost certainly the manufacturer data sheet.

Small 45.6 KB PDF named 2SD1902, a Japanese standard transistor number; despite the schematic label it is most probably a short datasheet.

Component documentation for the 2SK2920, a 409 KB PDF filed under schematics in this index but almost certainly a part datasheet.

PDF documentation, 431 KB, for the 2SK2883 N-channel FET, placed in the schematic section of the catalogue.

A 365 KB PDF for the 2SK2859, filed under the schematic type though it is most probably a manufacturer datasheet. Nothing other than the part number appears in the name.

The 2SK2854 transistor is documented in this 125 KB PDF, indexed under schematics but almost certainly a datasheet. The name states only the part number.

A compact 134 KB PDF titled with the part number 2SK2839 and catalogued as a schematic.

Datasheet-type PDF for the 2SK2740, 138 KB, with a 1-5 suffix in the name whose meaning is not stated, possibly an edition or page range.

Smaller 137 KB PDF tied to the 2SK2606, a JIS-style designation where 2SK indicates an N-channel field-effect transistor.

PDF document for the 2SK2374 part, filed under schematics but named after a Japanese-registered semiconductor rather than a board.

Part-number-only PDF for the 2SK2323, 23.2 KB, placed in the schematic category of the index.

Small 30.0 KB PDF covering the 2SK2047 transistor. Under the JIS naming system the 2SK prefix marks an N-channel FET, so this is best treated as a part datasheet rather…

Documentation for the 2SK2036 in a 326 KB PDF. Parts beginning with 2SK are N-channel field-effect transistors under the Japanese JIS numbering, so this file should be…

The 2SK2035 transistor is the subject of this 295 KB PDF, most likely the manufacturer datasheet given that 2SK is the JIS prefix for N-channel FETs.

2SK1841 documentation in PDF form, 90.4 KB in size and listed as a schematic. The 2SK designation in the Japanese JIS system indicates an N-channel FET, so expect…

A 291 KB PDF dedicated to the 2SK1830. The 2SK code is the Japanese JIS designation for N-channel field-effect transistors, so this is almost certainly a datasheet…

Document for the 2SK1806 in PDF format, 136 KB, catalogued as a schematic. The 2SK code marks an N-channel FET under JIS naming, so the contents are likely a component…

An 88.5 KB PDF on the 2SK1738 transistor. In the JIS system, 2SK designates an N-channel FET, so this file is most likely the datasheet rather than a circuit schematic.

A compact 32 KB PDF named 2SK1447LS, filed as a schematic. It appears to cover a variant of the 2SK1447 carrying an LS suffix, whose meaning the name does not explain.

A 29.4 KB PDF for the 2SJ569LS, catalogued as a schematic though it is named in the style of a component datasheet.

The 2SJ339 appears in this small PDF of roughly 40.7 KB. The name carries only the part number, with no hint of the equipment it came from.

The 2SD1294 is the only detail this 209 KB PDF name provides; the file is filed as a schematic but corresponds to a transistor part number.

Part-number reference for the 2SC4433 in PDF form, about 71.5 KB. The name gives no board or device, only the JIS designation, where 2SC denotes an NPN bipolar…

PDF for the 2SC4417 carrying an _E suffix whose meaning the name does not explain, sized 40.7 KB.

Datasheet-style PDF of 44.0 KB for the 2SC4391, filed as a schematic; the trailing _E suffix in the name is not explained and could denote an edition or language…
