Schematic for the Sony MBX-224 mainboard used in the M960 and M970 projects, marked as the H model at revision SA.

Part datasheet, most likely, for the 2SK2837, provided as a 426 KB PDF and indexed as a schematic.

Only 29.3 KB, this PDF named 2SK2380 sits under schematics but is most likely a brief datasheet for an N-channel FET, per the Japanese JIS 2SK prefix.

Covering the 2SC4632, this 89.2 KB PDF sits in the schematic category, yet its name matches a transistor part number.

A 297 KB PDF describing the 2SC4251 transistor. The name contains just the part number, so the issuing manufacturer and revision must be read inside the document.

Combined PDF, 53.0 KB, whose name lists two part numbers, 2SB1189 and 2SB1238, suggesting one data sheet covering both transistors. It is filed as a schematic.

Covering the 2SB1018A, this 233 KB PDF is indexed as a schematic but describes a single transistor.

Modified 2.1 channel amplifier schematic, a 90.6 KB PDF; the title does not say which original design was altered or which ICs are used.

This 55 KB PDF is labelled 2SK2220 and indexed under schematics, though a part-number name usually means the datasheet of a single semiconductor.

Indexed as a schematic, this 107 KB PDF refers to the 2SK1440, and the name states nothing beyond the part number.

Short 41.5 KB PDF for the 2SB1050, with an _E suffix whose meaning the name does not explain, possibly a language or edition tag.

Part sheet for the 2SB1377, 53.2 KB in PDF form, with an _E suffix in the name whose meaning is not stated and may reflect an edition or language version.

PDF schematic for the Gigabyte GA-H61M-USB3-B3 motherboard, revision 2.0, as shown by the R20 suffix.

Labelled 2SD2526, this 192 KB PDF contains reference data for a Japanese-coded transistor rather than a device-level circuit.

Datasheet for the 2SC4214 transistor, supplied as a 279 KB PDF. The file name holds nothing beyond the part number, so the manufacturer, package and target equipment…

Schematic for the ASUS NR2201ZE board, revision 2.1, as a large 18.2 MB PDF. The name names only the project code and not the retail model, so match it to the board…

PDF schematic for the ASUS UX430UN, UX430UNR and UX430UAR, revision 1.0, packed in a 2.31 MB RAR.
