Small 67.8 KB PDF for the 2SD1854, a part number in the Japanese 2SD series of NPN bipolar transistors, so it is really a datasheet rather than a full schematic.

Datasheet for the 2SD2258 NPN bipolar transistor, supplied as a 56.8 KB PDF and filed under schematics.

A 29.2 KB PDF documenting the 2SD2639 part, catalogued as a schematic. Nothing beyond the type number is stated in the name.

Covering the 2SD1817, this 75.8 KB PDF is indexed as a schematic but by name is a component datasheet. No maker or revision is indicated.

PDF document of 41.0 KB for the 2SD2185 transistor, with an _E suffix in the file name that is not decoded here.

The 2SD2598 transistor is covered in this 59.3 KB PDF, whose name ends in an _E suffix.

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.

Datasheet-type PDF for the 2SD1878, 90.6 KB, placed in the schematic category of the index. The name contains nothing beyond the part number.

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

Named 2SD2426, this 69.1 KB PDF is filed as a schematic, though the 2SD prefix follows the Japanese JIS code for NPN bipolar transistors and points to a single-part…

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 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.

The 2SK2545 is the subject of this 415 KB PDF, catalogued as a schematic but by its name a discrete transistor document.

Covering the 2SK2459N, this 138 KB PDF sits in the schematic section but by its name is a transistor datasheet; 2SK is the Japanese JIS prefix for N-channel field-effect…

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…

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

A 39.6 KB PDF for the 2SC5216, with an _E tag in the name that is not explained. It is listed as a schematic, but the name points to a transistor datasheet.

A 42.8 KB PDF for the 2SC5639, placed under schematics although its name is a bare part number pointing to a transistor datasheet.

Smallest of the batch at 30.8 KB, the PDF named 2SC5607 is presumably a concise datasheet for that NPN transistor despite being labelled a schematic.

For the 2SC5534 transistor, this 44.8 KB PDF sits in the schematic category but, going by the JIS 2SC code for NPN bipolar devices, is the part datasheet.

Catalogued as a schematic, this 45.8 KB PDF is named after the 2SC5503, a part number in the Japanese 2SC series used for NPN bipolar transistors.

A 39.3 KB PDF for the 2SC5490 component, which belongs to the 2SC range of NPN bipolar transistors under Japanese JIS numbering.

Catalogued as a schematic, this 100 KB PDF is named after the 2SC4031 and is most likely its datasheet. JIS numbering uses 2SC for NPN bipolar transistors.

Component reference in PDF form for the 2SC4002, 77.6 KB, filed in the schematic category.

Datasheet PDF, 81.8 KB, for the 2SC3997 transistor, placed in the schematic listing. JIS numbering uses 2SC for NPN bipolar transistors; nothing else, such as maker or…
