Part 2SC5043, a JIS-numbered NPN bipolar transistor, is the subject of this 106 KB PDF, which the index files as a schematic but which is presumably a datasheet.

A 79.7 KB PDF for the 2SC3950 transistor, placed in the schematic category though the part-number name indicates a component datasheet.

Reference PDF for the 2SC3648 transistor, 120 KB. Under JIS naming, devices starting with 2SC are NPN bipolar transistors.

A 349 KB PDF named for the 2SC2670 transistor and catalogued as a schematic, most likely containing the device datasheet. JIS 2SC numbering identifies NPN bipolar parts.

Listed under schematics, this 52.8 KB PDF refers to the 2SB1675, a PNP transistor in the Japanese JIS numbering system, so its content should be the part datasheet.

Reference PDF for the 2SA1345 transistor, filed under schematics but most likely a component datasheet.

Reference PDF covering the 2SA2097 transistor, 150 KB in size and filed as a schematic though it is component data.

PDF datasheet of 42.8 KB for the 2SA1011 transistor, catalogued in the schematic category though it is really component reference data.

A 444 KB PDF for the 2N7000 carrying the tag Sam, which probably identifies the manufacturer that issued it, although the name does not expand the abbreviation.

The 2N6794 PDF, around 129 KB, sits in the schematic section but its name holds only a JEDEC semiconductor number. No host equipment, revision or board code is stated.

A 129 KB PDF identified solely by the JEDEC number 2N6786, listed among schematics. The name gives no device model, board or revision.

Catalogue entry for 2N6784, a 131 KB PDF filed under schematics though its name is just a JEDEC semiconductor part code. No product or board details are given.

PDF datasheet, 48.1 KB, for the part named 1T3797, indexed among schematics. The 1T prefix follows the Soviet designation pattern used for germanium transistors, though…

Data reference for the 1SV239, a 70.1 KB PDF whose trailing underscore carries no meaning. The index files it as a schematic.

15mq040n is the name on this 94.2 KB PDF, which the catalogue files as a schematic. The code resembles International Rectifier or Vishay surface-mount Schottky rectifier…

Filed as a schematic, this 326 KB PDF carries the part number 12CLQ150 and is most likely the component datasheet for that device.

PDF schematic for FL1 tagged MP, likely mass production, dated 0820 with revision R1A, about 1.02 MB.

Reference PDF of 598 KB for the CD4042BE, a CMOS quad clocked D latch in the 4000 series; the E suffix usually indicates the plastic DIP package.

Data for the 2SD2184, an NPN low-frequency bipolar transistor according to the Japanese 2SD numbering prefix, supplied as a 43.8 KB PDF.

This 145 KB PDF carries the 2SD1722 part number and nothing more, so it is best treated as that transistor's datasheet.

Reference document for the 2SK2679, a 393 KB PDF in the schematic category. The 2SK prefix is the Japanese JIS registration for N-channel field-effect transistors, so…

A 166 KB PDF covering the 2SK1961 transistor. The 2SK series in the JIS system denotes N-channel FETs, so this schematic-categorised file should be read as a component…

PDF reference, 105 KB, for the 2SK1813 transistor. In the Japanese JIS scheme, 2SK designates an N-channel field-effect transistor, so this is probably its datasheet.

Documentation for the 2SK1431, a part whose 2SK prefix places it among N-channel FETs under Japanese JIS numbering.

Component documentation for the 2SK1033, a 34.4 KB PDF file. The 2SK series covers N-channel field-effect transistors in the Japanese designation system, and a…

PDF of 42.8 KB for part 2SJ585LS, listed under schematics. JIS semiconductor coding assigns 2SJ to P-channel FETs, so this is most probably a datasheet with ratings…

This catalogue entry covers a 118 KB PDF called 2SJ192, a Japanese JIS part number for a P-channel field-effect transistor; although filed under schematics, it is likely…

Small 98.3 KB PDF for the 2SC5300 part. The 2SC prefix is the Japanese JIS registration for NPN bipolar transistors, so despite being listed as a schematic, the file is…
