PDF reference of 221 KB for the 2SK2909, catalogued as a schematic. Only the part number is present in the name, with no maker or revision indicated.

Component sheet for the 2SK2886 transistor, delivered as a 424 KB PDF and filed in the schematic category. The name carries only the part number.

PDF document for the 2SK2775, filed under schematics although the part number points to a component datasheet rather than a board drawing.

Component document for the 2SK2611, a part number in the Japanese JIS scheme where the 2SK prefix marks an N-channel field-effect transistor.

Compact 33.0 KB PDF on the 2SK1834 transistor. The 2SK prefix belongs to the Japanese JIS designation system and means an N-channel field-effect device, so the content…

Datasheet-style PDF for the 2SK1412LS, a Japanese 2SK-series N-channel field-effect transistor, filed in the index under schematics.

At just 31.4 KB, the PDF named 2SJ499 is probably a short datasheet or summary sheet, even though it is filed as a schematic.

Catalogued as a schematic, this 93.1 KB PDF is named only after the part number 2SJ281, which follows the Japanese JIS scheme where the 2SJ prefix denotes a P-channel…

At 294 KB, this PDF is larger than its neighbours but still identified only by 2SJ167, a Japanese JIS number for a P-channel field-effect transistor.

PDF document of 41.7 KB for the 2SC4737, filed in the schematic category but named after a part rather than a board.

Filed under schematics, this 98 KB PDF is named after the part number 2SC4671, which follows the Japanese JIS designation for an NPN bipolar transistor.

This 39.4 KB PDF is labelled 2SC4656 with an E suffix. The E most likely marks an English edition from a Japanese maker, but the name does not say so outright.

Datasheet in PDF form for the 2SC4696, filed in the index under schematics although the name points to a discrete part document rather than a board diagram.

The name 2SC4172 is a Japanese JIS semiconductor designation, so this 109 KB PDF, though filed as a schematic, should be the reference sheet for an NPN bipolar…

The largest of this group at 334 KB, this PDF is named only 2SC4117 and, while labelled a schematic, should be the datasheet for that NPN bipolar transistor under…

Small 95.8 KB PDF for the 2SC4109, indexed with the schematics. The file name gives nothing beyond the part number; the 2SC prefix identifies an NPN bipolar transistor…

Small 30.5 KB PDF for the 2SC5808 part, an NPN bipolar transistor per the Japanese 2SC designation.

Datasheet-sized PDF of 38.0 KB for the 2SC5474, with an _E suffix in the name that likely marks an English edition; that reading is an inference.

The 2SC3552 transistor is documented in this 121 KB PDF, catalogued under schematics though it is a component datasheet.

PDF of 41.2 KB for the 2SC3130, with an extra E suffix in the name whose meaning is not stated; it may mark an edition, language or variant, so check inside.

Compact 128 KB PDF bearing the part number 2SC2983, indexed as a schematic. Under the Japanese JIS naming convention a 2SC number denotes an NPN bipolar transistor, so…

Catalogued among schematics, this 54.5 KB PDF is named for the 2SB642, which the JIS 2SB prefix marks as a PNP transistor; the document is therefore expected to be a…

Datasheet for the 2SB1658, filed in the index as a schematic but in practice a component data document in PDF form, 48 KB.

The 2SB1642 PNP transistor is documented in this 181 KB PDF, listed as a schematic though it is a part datasheet.

English-edition datasheet, judging by the _E suffix, for the 2SB1599 PNP bipolar transistor, 43.5 KB in PDF.

Component data for the 2SB1527 in PDF form, roughly 73 KB, catalogued as a schematic though the bare part number suggests a datasheet.

Covering the 2SA1433, this 78.1 KB PDF is indexed as a schematic but is most likely a component data sheet.

Datasheet for the 2SA879 in a 49.9 KB PDF; the trailing _E in the name probably denotes an English version, though the name does not confirm it.

PDF of 47.9 KB filed as a schematic and named for the part 2PA733, revision 4 by its suffix.

Small 70.2 KB PDF for the 1SS396 component, placed in the schematic category. Given the 1SS numbering, the Japanese series for small-signal diodes, it is most likely a…

A 52.8 KB PDF labelled 1SS351, catalogued as a schematic though the name is just a component number.

The file name gives only 1SS348, a part number in the Japanese 1SS small-signal diode series, common in Toshiba catalogues.

PDF schematic for the Lenovo B490 laptop, roughly 1.95 MB. The name omits the motherboard number and revision, so read the board code inside and confirm it against the…

Small 186 KB PDF schematic for the earphone and charging daughterboard used in E14 and E15 machines. No vendor, generation or board number is given in the name.

Acer Aspire 4710 schematic supplied as a 1.29 MB PDF. No board number or revision appears in the name, so open the title block and compare its project code with the…

Schematic diagram of the Quanta BL6 notebook motherboard, 5.02 MB PDF. The name carries just the Quanta project code, with no revision, brand or model indicated.

Compal LA-4105P schematic, 1.48 MB PDF, with 4085e also in the name, possibly a related model or project code.

Circuit schematic for the Sony VAIO VPCYB3V1E notebook in PDF format, about 1 MB in size.

Schematic for the Toshiba Dynabook Qosmio F40, with the identifier 87CBL included in the file name.

Schematic document for Sony VAIO laptops identified as M630 and M640, supplied as a 1.11 MB PDF.
