Here is the 389 KB PDF for the 2SK1359 MOSFET, part of the Japanese 2SK family of N-channel field-effect transistors.

PDF datasheet for the 2SK444, sized 92.5 KB and listed in the schematic category. The 2SK prefix places it in the Japanese JIS series of N-channel FETs, so the document…

Reference sheet for the 2SC4736 in PDF form, 104 KB in size. Although catalogued as a schematic, the number follows the JIS scheme where 2SC marks an NPN bipolar…

A 106 KB PDF named only 2SC4459, placed in the schematic category of the index. That JIS-style code marks an NPN bipolar transistor designed for high-frequency…

Datasheet-style PDF named for the 2SC4430, sized 108 KB and listed as a schematic in the index.

Datasheet-style PDF covering the 2SC5027, 241 KB in size and placed in the schematic category. The name holds only the part number, with no revision or suffix.

Datasheet-style PDF of 127 KB for the 2SC3708, an NPN transistor according to its JIS 2SC prefix, although the index files it as a schematic.

File for the 2SC5321 in PDF form, 122 KB, listed among schematics yet named like a discrete-component datasheet.

A 320 KB PDF dedicated to the 2SC3011, indexed as a schematic but most likely a transistor datasheet. Nothing besides the part number appears in the name.

Reference PDF of 175 KB for the 2SC2235, a JIS-style designation where 2SC denotes an NPN bipolar transistor.

A small PDF of 40.7 KB for the 2SA1538, a JIS-coded transistor; despite the schematic label, a file named only by part number is normally a datasheet.

The 2SA1430 transistor is covered by this 182 KB PDF, the same size as its 2SA1431 neighbour, which suggests a shared document layout.

Larger than most of its neighbours at 477 KB, this PDF covers the 2N4033 and may contain extra graphs, scanned pages or a multi-part data book extract; the name alone…

Listed under schematics, this 69.1 KB PDF covers the 1SS187 part number, with an uninformative trailing underscore.

Labelled only 123nq, this 98.5 KB PDF is catalogued as a schematic but names no device, board or revision.

Named simply 50SQ, the 132 KB PDF in the schematic category covers what looks like a component family rather than a specific device; no brand, model or board is given.

Quanta SW7 motherboard schematic in a 1.24 MB PDF. The file name gives neither a revision nor the laptop brand, so match the SW7 code and revision printed on the PCB…

PDF schematic for the Foxconn H61MXV desktop motherboard, revision A, compressed in a 1.11 MB RAR.

Service manual for the Fluke 87V digital multimeter, a 1.18 MB PDF. Manuals of this kind normally cover specifications, performance verification, calibration adjustment…

PDF document of 885 KB whose Persian file name translates as oscilloscope, which suggests a guide or tutorial on using an oscilloscope rather than a schematic for a…

Schematic diagrams for the Lenovo S90 smartphone, archived as RAR at 4.88 MB; unlike several sibling files, the name mentions only diagrams, not a service manual.

Training course material on basic electronics repair, 7.26 MB PDF, catalogued with schematics although it is an educational guide rather than a board diagram.

Component documentation for 5HP02M, delivered as a 40.7 KB PDF. Despite the schematic label, the name is a bare part number with no board or brand information, so treat…

PDF reference for the 2SK583, a 57.1 KB file indexed as a schematic but in practice a transistor datasheet, since the 2SK prefix marks an N-channel field-effect…

Specification sheet for the 2SD874 transistor in PDF form, about 44 KB, catalogued with the schematics but actually a component datasheet.

At 153 KB, this PDF named 2SC4399 is presumably the datasheet for that NPN bipolar transistor, even though the index lists it as a schematic.

Part 2SC3991 is the only information carried by this 113 KB PDF, which the index lists as a schematic although the name points to a discrete component datasheet.

A 94.9 KB PDF for the 2SC3088, filed as a schematic but in practice probably a component datasheet. Its name contains just the part number.

A 71.2 KB PDF with data for the 2N2222, filed with schematics in this index. The 2N2222 is a staple NPN small-signal transistor used for switching relays, LEDs and logic…

PDF document of 203 KB filed as a schematic and named only 80CNQ035A. No device, motherboard number or revision is stated, and the code follows the pattern of a…

Named 322CNQ and catalogued as a schematic, this 64.9 KB PDF contains no device or board details in its name.

A schematic-category PDF of 223 KB named 20CTQ, without any device model, board number or revision in the name.

A 1.46 MB schematic PDF named only J7 Pro, with no model code, brand or board revision in the name; J7 Pro is a Samsung Galaxy model name.

Sony schematic PDF, 9.78 MB, with a short, uninformative name that does not state the model or board number.
