Schematic diagram for the HP NX6120 notebook in PDF format, 941 KB. Only the model is given in the name, with no board number, ODM project code or revision, so check the…

Small 197 KB PDF for the Gigabyte GA-Z170X-Gaming G1, revision 1.0, labelled as boardview despite the PDF format.

Part document for the 2SC4517, a 27.9 KB PDF listed as a schematic; the name holds only the part number.

Datasheet-style PDF for the BU2508DX, roughly 80 KB, indexed under schematics. This is a well known horizontal deflection transistor for CRT TVs and monitors, and the D…

Named 3LN02C, this 41.8 KB PDF is filed among schematics but its name is a component-type code with a C suffix and gives no device or board details.

A fairly detailed 200 KB PDF for the 2SD2352, a JIS-numbered NPN transistor, where the 2SD prefix denotes NPN low-frequency parts.

A compact 23.3 KB PDF for the 2SK2772, an N-channel FET according to the JIS 2SK naming convention, catalogued here as a schematic.

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…

The name 2SK1446LS marks this 32 KB PDF as covering an LS-suffixed version of the 2SK1446.

Datasheet-style PDF for the 2SK669, a part number in the JIS 2SK series used for N-channel field-effect transistors, listed in the index as a schematic.

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.

The 2SJ419 is covered by this 100 KB PDF, filed under schematics though the part number points to a discrete transistor datasheet.

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.

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…

Stored under schematics, this 93.8 KB PDF is named for the 2SC4123 and is expected to hold the transistor's datasheet rather than a circuit drawing.

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.

Named for the 2SC4003, this 79.4 KB PDF is listed as a schematic but appears to be a transistor datasheet.

A 129 KB PDF filed under schematics, though its name, 2SC3807, is simply a transistor type number.

The 2SC3606 is the only detail given by this 464 KB PDF, catalogued as a schematic yet functionally a part datasheet.

Covering the 2SC3599, this 124 KB PDF is a discrete transistor datasheet even though it is filed as a schematic.

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

At 192 KB this PDF is somewhat larger than its neighbours and covers the 2SC3142 transistor, an NPN bipolar part under JIS 2SC numbering.

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.

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

Reference sheet for the 2SA1182 transistor, stored as a 202 KB PDF. The 2SA prefix belongs to the JIS numbering system and identifies a PNP bipolar device, so the…

Compact 23.8 KB PDF for the 2SA1870 PNP transistor, named in lowercase with only the part number.

Reference PDF for the 2SA1127 transistor, 41 KB, filed in the schematic category, with an _E suffix in the name whose meaning is not stated.

Short 49.9 KB PDF document for the 2N6284, a JEDEC-registered discrete semiconductor, catalogued as a schematic though it is most likely the part's datasheet.
