Datasheet in PDF form, 74.1 KB, for the 2SD1853 transistor from the Japanese 2SD family of NPN bipolar parts, filed here as a schematic.

Datasheet for the 2SD2650 transistor, a 29.7 KB PDF filed in the schematic category. The file name states the part number and nothing else.

A 43.6 KB PDF tied to the 2SD1820, including an E suffix that the name does not explain.

Small 27.3 KB PDF for part 5LN02C, listed as a schematic though it is evidently a discrete-device datasheet.

PDF specification of about 78 KB for the 2SD1799 NPN transistor, named in the Japanese 2SD series and companion in numbering to the neighbouring 2SD1800 sheet.

For the 2SD2499 transistor, this 269 KB PDF provides component-level data despite its schematic category.

Named for the 2SD2462, this 184 KB PDF is effectively a datasheet for a Japanese-registered transistor.

Covering the 2SD1668, this 104 KB PDF is listed as a schematic, though the name is a discrete transistor code.

Carrying only the part number 2SD1885, this 93.4 KB PDF is filed as a schematic, though it reads as a transistor datasheet by name.

Component documentation for the 3N246, a 43.6 KB PDF indexed as a schematic. The name follows the JEDEC 3N numbering used for four-terminal semiconductor devices, and…

Component sheet covering the 3N254, delivered as a 42.2 KB PDF and indexed as a schematic. JEDEC numbers beginning with 3N denote registered devices having four leads.

Small 40.1 KB PDF for the 2SD1957, written in lower case in the original name and catalogued under schematics.

Component datasheet in PDF form, 57.8 KB, for the 2SD1478, though the index files it under schematics.

The 2SK2843 is the only detail in this file name, an N-channel FET designation under the Japanese JIS scheme.

Datasheet-style PDF of 27.2 KB for the 2SK2682, a JIS-designated N-channel FET; it is listed under schematics but describes a single component.

Covering the 2SK2507, this 422 KB PDF belongs to the JIS family of N-channel field-effect transistors denoted by the 2SK prefix.

Reference PDF for the 2SK2466, 424 KB in size, belonging to the JIS N-channel FET family denoted by 2SK. The name contains only the part number.

A 316 KB PDF dedicated to the 2SK2401, sorted under schematics but most likely a part datasheet given its JIS-format number; 2SK designates an N-channel FET.

Sized at 111 KB, a PDF for the 2SK2394 that the index lists under schematics, though its JIS-style part number indicates a datasheet for an N-channel field-effect…

Reference sheet in PDF form for the 2SK2349, sized 54.7 KB and listed in the schematic category.

Listed as a schematic, this 422 KB PDF carries the part number 2SK2232 and is most likely the datasheet for that N-channel FET.
