PDF of 699 KB carrying the uninformative name null, so nothing about the device, brand or board can be learned without opening it.

Quanta schematic for the ZM3 project, board DA0ZM3MB8D0 at revision 3A, in PDF form. Quanta board numbers start with DA0 followed by the project code and MB, and the…

Scanned PDF of the September 2006 issue of AudioXpress, the audio electronics magazine, filed here under schematics.

2.1 channel hi-fi audio amplifier circuit by Technical Mriganka, a 164 KB PDF. The title does not name the amplifier ICs or output devices, so identify them from the…

Schematics for a device identified only as K520, delivered as a fairly large ZIP archive of 34.8 MB.

Spanish table of SMD equivalences, a cross-reference for surface-mount parts rather than a device schematic. No brand or board is named.

Spanish electronics course PDF focused on tablets, about 2.73 MB, filed under schematics though it reads as training material.

Very large 7z archive of 1.61 GB whose Russian name simply means schematics, with no brand, model or board number given.

A 386 KB PDF covering capacitors and inductors, filed as a schematic but by its name an educational reference rather than a device diagram.

PDF schematic section for the Qualcomm SM4375 processor, as named, likely a reference or handset excerpt focused on the SoC block.

PDF schematic for the SM7325 processor, 1.81 MB, without any handset model or board number in the name.

Repair guide, marked RG, for the TF500T tablet, packaged as a 632 KB PDF. Such Asus guides generally feature board photos with labelled key components, voltage values at…

The 2SD2252 is the subject of this 88.6 KB PDF, indexed as a schematic but best treated as a transistor datasheet.

The 2SD592 NPN transistor is documented in this 50.3 KB PDF, which the catalogue lists as a schematic.

A small 33.3 KB PDF covering the 2SD330 transistor, listed as a schematic though it documents a single discrete part. The name carries no other details.

A 43.6 KB PDF tied to the 2SD1820, including an E suffix that the name does not explain.

A 44.1 KB PDF for the base 2SD2177 transistor, the name also carrying an _E suffix. The 2SD prefix in the Japanese JIS scheme marks an NPN bipolar device for…

Small 27.3 KB PDF for part 5LN02C, listed as a schematic though it is evidently a discrete-device datasheet.

PDF of roughly 41 KB for the component coded 5HP02SP, catalogued as a schematic though the name points to a single semiconductor part.

A 40.6 KB PDF for the component 5HN02C. Although classed as a schematic, the file name contains just a part code, with C probably denoting the package, and states no…

The 2SD1724 part number is all the name gives, and the 145 KB PDF is tagged as a schematic, though a file named this way is normally a transistor datasheet.

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

For the 2SD2499 transistor, this 269 KB PDF provides component-level data despite its schematic category.

Named for the 2SD1618 transistor, a 116 KB PDF listed as a schematic but most plausibly the part's datasheet.

PDF of 184 KB bearing the part number 2SD1410A, kept in the schematic category but best treated as the transistor's datasheet, with the A suffix denoting a variant of…

A 90.1 KB PDF named after the 2SD1877 semiconductor and filed as a schematic, although its content is expected to be a component datasheet.

Component documentation for the 3N246, a 43.6 KB PDF indexed as a schematic. The name follows the JEDEC 3N numbering used for four-terminal semiconductor devices, and…

PDF sheet of about 42 KB for the 3N259, catalogued under schematics though the file name is simply a JEDEC part number.

The entry, 366 KB in PDF format, is named 2SK161 and, despite its schematic label, should contain the datasheet for that JIS-coded component.

Named 2SK3491, this 29.8 KB PDF is most likely the datasheet for that JIS-numbered device, despite being listed as a schematic.

The 2SK2843 is the only detail in this file name, an N-channel FET designation under the Japanese JIS scheme.

Indexed in the schematic category, this 141 KB PDF is named for the 2SK2792. Japanese JIS numbering uses 2SK for N-channel field-effect transistors, pointing to a…

PDF of 415 KB describing the 2SK2741, catalogued with schematics but in substance a part datasheet, as 2SK denotes an N-channel FET in JIS numbering.

The 2SK2598 is documented in this 418 KB PDF, listed among schematics but named only by part number, which indicates a component datasheet.

A 410 KB PDF describing the 2SK2542, a JIS-numbered part where 2SK signifies an N-channel FET.

Short PDF of 30.9 KB for the 2SK2538, with the part number written in lowercase in the original name.

Reference PDF for the 2SK2466, 424 KB in size, belonging to the JIS N-channel FET family denoted by 2SK. The name contains only the part number.
