PDF schematic named only ME4812, 852 KB, with no brand, model or revision information. The code could be a board or project identifier, but the name alone cannot confirm…

Schematic PDF of 672 KB whose name only gives C660, most likely a model designation, with no brand, board number or revision stated, so the exact device has to be…

SM7250 processor schematic in PDF format, 1.37 MB, with no handset model or revision named.

Small 57.3 KB PDF for the 2SC5060, filed under schematics though the name suggests a transistor part sheet.

PDF document for the IRFP260 power MOSFET, catalogued under schematics although the name points to a component datasheet.

Document for the 3DD304X, stored as a 489 KB PDF and catalogued under schematics, though the name suggests a component datasheet.

At 312 KB, this PDF for the 2SD2638 is the largest in its series and is probably a full datasheet with curves and outline drawings, though it is filed under schematics.

Reference sheet in PDF form, 141 KB, for the 2SD2198 transistor. The file is indexed as a schematic but is most likely a datasheet.

Small 27.4 KB PDF named after the part code 5LN01C, indexed as a schematic though it reads like a discrete-component datasheet.

Small 39.9 KB PDF for the 2SD2474, carrying an _E suffix whose meaning the name does not state; it may reflect a language or edition marker.

Small PDF of 92.1 KB filed under schematics, though its name is simply the part number 2SD1998, so it is almost certainly a component datasheet rather than a board…

A 115 KB PDF named after the 2SD1625 part number, catalogued as a schematic but in practice most likely the transistor's datasheet.

PDF covering the 3SK189, about 178 KB in size and listed in the schematic category, though the name points to a single component datasheet.

PDF of 43.6 KB for the 3N252, listed under schematics though the name is a bare JEDEC part number.

Part reference for the 3N250, stored as a PDF of about 43.6 KB and catalogued in the schematic section.

PDF reference of about 41.6 KB for the 3LN01C, indexed as a schematic but by name a single semiconductor datasheet.

A compact 106 KB PDF covering the 2SK2919 transistor, indexed as a schematic though the name points to a manufacturer datasheet.

PDF documentation, 431 KB, for the 2SK2883 N-channel FET, placed in the schematic section of the catalogue.

A 365 KB PDF for the 2SK2859, filed under the schematic type though it is most probably a manufacturer datasheet. Nothing other than the part number appears in the name.
