Component reference for the 2SD2635, a 35.2 KB PDF listed among schematics. The file name offers only the part number, with no manufacturer or revision given.

Filed as a schematic, this 53 KB PDF is named after the 2SD1725 part number, so it is most likely a component datasheet rather than a board diagram.

A compact 49.9 KB PDF for the 2SD2074, with an _E suffix in the name that is not explained and could indicate a language edition or document revision.

Small 56.9 KB PDF for the 2SD1679, with an extra E suffix in the name that is not explained further.

At just 33.5 KB, this PDF for the 2SD1623 is a short document listed as a schematic, though the part-number name suggests a compact datasheet.

Datasheet-style PDF for the 2SD1423, 41.0 KB, stored as a schematic; the trailing _E in the name is not explained by the file itself.

A 32.8 KB PDF for the 3SK273, indexed as a schematic though it is likely a manufacturer datasheet.

Datasheet-style PDF for the 3LP02N, about 41.5 KB and listed as a schematic. No device, brand or board details appear in the name beyond the part code itself.

Reference sheet of 41.7 KB in PDF format for the 3LP02M, filed among schematics though it is effectively a component datasheet.

Datasheet-style PDF for the 2SD1994A transistor, filed in the schematic category of the index.

Datasheet PDF, 43.0 KB, for the 2SD2321, with an _E suffix carried over from the original name, though the suffix itself is not explained.

File name 2sk198 is a JIS semiconductor number, so this 31.8 KB PDF, though catalogued as a schematic, is best treated as a brief component datasheet.

PDF document of 299 KB named for the 2SK117, most likely a datasheet even though the catalogue lists it as a schematic.

The 34.0 KB PDF named 2SK3557 is indexed as a schematic, but its name is a JIS component number, so it is almost certainly a datasheet.

The file, a 28.4 KB PDF, is named 2SK3485 and catalogued as a schematic; the name is a JIS semiconductor number, so treat it as a short datasheet.

Part documentation for the 2SK2914 in PDF form, 396 KB, placed in the schematic section of the index.

A 318 KB PDF covering the 2SK2882, listed under schematics but almost certainly a datasheet given the bare part number in its name.

Covering the 2SK2865, this 424 KB PDF sits in the schematic category but, judging by its name, is the component datasheet.

Listed as a schematic, this 412 KB PDF carries only the part number 2SK2845 in its name.

The 2SK2792 part number appears here with an unexplained 1-5 suffix, possibly a page range or edition marker.

The 2sk2790 name on this tiny 21.3 KB PDF is the only information provided. Filed as a schematic, it most probably holds a brief datasheet for an N-channel field-effect…

Part reference for the 2SK2607, an N-channel FET according to the 2SK prefix of the JIS numbering convention.

Reference sheet for the 2SK2599 in a 418 KB PDF, placed in the schematic section although the name holds nothing but the part number.

Compact 30.7 KB PDF for the 2SK2593, filed as a schematic though the lowercase name is simply a semiconductor part number.

PDF for the 2SK2463 carrying a _1-5 suffix, 136 KB in size; the name does not explain the suffix, which may refer to pages or an edition of the document.

PDF reference for the 2SK2339 transistor, 35.9 KB, catalogued under the schematic type.

A PDF of about 88 KB for the 2SK2154, filed under schematics but most likely a component datasheet, since the name is just the part number.

Reference sheet for the 2SK2046, supplied as an 88.4 KB PDF. The 2SK designation belongs to the Japanese registration scheme for N-channel field-effect transistors…

The 2SK2010 transistor is documented in this 90.1 KB PDF, filed among schematics but in substance a datasheet for an N-channel FET, as the JIS 2SK prefix indicates.

Datasheet in a 33.2 KB PDF for the 2SK1967, a Japanese-registered N-channel field-effect transistor indicated by the 2SK prefix.

A 95.0 KB PDF named after the 2SK1908, listed in the schematic section of the index. Since 2SK is the Japanese registration prefix for N-channel FETs, treat it as the…

Reference PDF covering the 2SK1842, a part number in the JIS 2SK series used for N-channel field-effect transistors.

Datasheet PDF, 292 KB, for the 2SK1829 transistor. Under JIS naming, 2SK marks an N-channel FET; the file name gives only the part number, with no maker or package…

PDF, 121 KB, for the 2SK1474 transistor. Japanese 2SK numbering denotes an N-channel field-effect device, so although the index category is schematic, the content is…

Part-number PDF for the 2SK1471, 92.5 KB in size and labelled as a schematic in the index.

The 2SK1449 gives this 109 KB PDF its name, and nothing else is stated. It is filed as a schematic, though it is probably the device data sheet.

The 2SK1375 N-channel field-effect transistor is covered by this 150 KB PDF, filed under schematics in the catalogue.
