Datasheet for the 2SD2271 transistor, a 219 KB PDF and one of the larger files in this 2SD group, so it probably includes detailed characteristic curves.

Small 27.9 KB PDF for the 2SC4630LS, sorted into schematics though it reads as a transistor datasheet.

Very small PDF, 29.2 KB, for the JEDEC-registered 2N6076, indexed as a schematic but presumably the part's datasheet, possibly only a page or two.

PDF schematic of 972 KB titled PLATINUM with SCH 2.2.11 in its name, most likely a schematic numbered or versioned 2.2.11, although the device type and maker are not…

Quanta schematic for the LG3-5 project, board DA0LG3MB6G0 at revision 2A, supplied as a PDF inside a 997 KB RAR archive; no laptop brand is given in the name.

Quanta schematic covering the HK8 and HK9 projects, revision R1A, dated January 17, 2013, in a 1.07 MB PDF.

A 213 KB PDF dedicated to the 2SC3657. By Japanese JIS convention the 2SC prefix denotes an NPN bipolar transistor; the file name gives only this number.

Datasheet-type PDF for the 2SC3333, 289 KB, though the index places it under schematics. The 2SC prefix follows the JIS convention for NPN bipolar transistors.

A 267 KB PDF for the 2SC3113, catalogued as a schematic but by its name most likely a component datasheet.

The 2SA1934 is documented in this 237 KB PDF, filed under schematics although the name carries only a component code.

Schematic of the MSI RTX 4090 graphics card, PCB MS-V510 revision 2.2, as a PDF compressed into a 2.93 MB RAR.

Circuit diagram for the Sony MBX-247 board, a design produced by Quanta under the project code HK1, revision 2A.

PDF of 129 KB for the 2SD1427, an NPN bipolar transistor in the 2SD series, indexed as a schematic but most likely a datasheet. The name gives no ratings or package.

The 2SD1829 is covered by this 154 KB PDF, filed under schematics although the name points to a discrete transistor datasheet.

The 2SD1823 is documented in this 40.5 KB PDF, whose name ends in an unexplained E suffix.

Titled in lowercase as 2sd1414, this 62.9 KB PDF is catalogued as a schematic, though a lone part number indicates a transistor datasheet.

Datasheet PDF for the 2SK1612, just 36.4 KB, indexed under schematics. The 2SK code marks an N-channel field-effect transistor in the Japanese part-numbering system; no…

Reference PDF of 111 KB for the 2SK1444, filed in the schematic section and most likely its complete data sheet.

The 2SC5684 part number heads this 126 KB PDF, which should be a component datasheet: 2SC is the Japanese JIS code for NPN bipolar transistors.

Named simply 2SC5045, this 108 KB PDF appears under schematics, but the number follows JIS transistor naming where 2SC denotes an NPN bipolar device, so it is likely a…

A 117 KB PDF specification for the 2SC3636. Parts carrying the 2SC prefix are NPN bipolar transistors under JIS naming.

Datasheet-type document in PDF for the 2SA1687, a Japanese JIS-registered transistor, listed under schematics at 143 KB.

Reference PDF, 38.3 KB, for the 2SB1335 transistor, listed under schematics although it covers a single semiconductor rather than a circuit board.

The 2SA1739 is named in this 44.6 KB PDF, listed among schematics although the JIS 2SA designation shows it is a PNP bipolar transistor datasheet.
