Topstar S42G schematic in PDF form, 1.22 MB. The file name carries no revision, so compare the title block revision with the code printed on your motherboard.

An 88.0 KB PDF for the 2SD1838, a Japanese-registered NPN bipolar transistor, best treated as a datasheet even though it is indexed as a schematic.

The 2SD2225 transistor is described in this 44.3 KB PDF, listed as a schematic in the catalogue. The _E tag in the name refers to an edition of the document.

Reference sheet for the 2SD2116 NPN transistor, supplied as a 74 KB PDF. Its name follows the Japanese JIS 2SD convention and carries nothing beyond the part number.

Reference document for the 2SD1662 transistor, 137 KB, PDF format, placed in the schematic category.

PDF document for the 2SD2028, 91.1 KB, filed in the schematic category. Only the part number is given.

The 2SD1622 PDF, 138 KB in size, sits among schematics, but a file named only by a semiconductor part number is very likely the device datasheet.

Part documentation for the 2SD1876 in PDF form, 89.6 KB, categorised under schematics. Only the part number is given in the name.

Part 2SK2399 is the subject of this 423 KB PDF, catalogued as a schematic but in all likelihood a datasheet, since under Japanese JIS numbering 2SK stands for an…

A 134 KB PDF identified solely as 2SK2219, placed in the schematic category but most likely a transistor datasheet.

Indexed under schematics, this 110 KB PDF carries the part number 2SK1447 and is likely its full component data sheet.

A small 98.7 KB PDF about the 2SK1416, catalogued under schematics but most likely a component datasheet.

A 420 KB PDF covering the 2SJ402, whose 2SJ prefix under Japanese JIS designation marks a P-channel field-effect transistor.

At 383 KB, this PDF documents the 2SJ360, indexed as a schematic but by name a transistor datasheet.

PDF of 56.2 KB named 2SD1391, a JIS designation for an NPN low-frequency bipolar transistor, and presumably its datasheet although indexed under schematics.

Separate from the UTC version, this 43.2 KB PDF covers the 2SD965 and bears an _E suffix that the name leaves unexplained.

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

Carrying only the part number 2SC5030, this 212 KB PDF is categorised as a schematic, but the JIS 2SC prefix identifies an NPN transistor and the file is most likely its…

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

Largest of the _E series at 59.4 KB, the 2SC3936 PDF is catalogued as a schematic but is named like a transistor datasheet, with the suffix usually indicating an English…

Reference sheet in PDF form, about 123 KB, for the 2SC5374 NPN transistor in the Japanese 2SC numbering series.

The 2SC3000 is the only detail carried by this 167 KB PDF, which is catalogued under schematics and most likely holds a datasheet.

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, 88.9 KB, documenting the 2SA1654 transistor; only the part number is present in the name.

Compact 39.7 KB PDF on the 2SB1370, indexed as a schematic though it documents one discrete device.

PDF documentation, 195 KB, for the 2SB907. Japanese JIS numbering assigns the 2SB prefix to PNP transistors meant for low-frequency applications.

Short 42.0 KB PDF describing the 2SB858 transistor, its name giving only the part number. Japanese JIS designations beginning 2SB denote low-frequency PNP transistors.

Reference PDF of 136 KB for the 2SA1406 transistor, catalogued among schematics. The 2SA prefix, by JIS convention, marks a PNP device in the high-frequency category.

PDF for the 2SA2066 transistor at about 201 KB, catalogued with schematics but representing a component datasheet.

PDF data for the 2SA1838, sized 87.4 KB and stored in the schematic category of the index.

A 91.7 KB PDF for the 2SA1831, placed in the schematic section of the catalogue. According to Japanese JIS numbering, 2SA designates a PNP bipolar transistor.

The 2SA1022 transistor is described in this 38.2 KB PDF, whose name includes an _E suffix; it is filed in the schematic category.

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

A 193 KB PDF for the 2SA950, catalogued as a schematic but carrying a JIS semiconductor designation.

For the 2SA1783 transistor, a 186 KB PDF sits in the schematic category, though the JIS designation makes it a part datasheet rather than a circuit diagram.

Reference sheet for the 2N681 semiconductor, stored as a 209 KB PDF and listed in the schematic category, though a 2N designation points to a single-component datasheet.

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.

Small 64.5 KB PDF named 2N6764, placed in the schematic category. Only the JEDEC semiconductor code is given, with no model, brand or board details.
