Large 962 KB PDF for the LM324P, the quad operational amplifier in a plastic DIP package, as the P suffix commonly indicates.

PDF of 137 KB for the 2SK2713, carrying a 1-5 suffix of unstated meaning, likely an edition or page marker rather than a different device.

The 2SK2035 transistor is the subject of this 295 KB PDF, most likely the manufacturer datasheet given that 2SK is the JIS prefix for N-channel FETs.

PDF of 33.4 KB describing the 2SK2016 transistor, an N-channel FET by its JIS 2SK prefix. It is catalogued as a schematic but is best used as a component datasheet.

The 2SK1489 named here is a discrete transistor code: under JIS numbering, 2SK denotes an N-channel field-effect transistor.

Reference PDF for the 2SK1457, filed under schematics and 122 KB in size. The file name carries only the part number.

The 2SK1456 is the only information in the name of this 124 KB PDF, which is indexed as a schematic.

A 177 KB PDF describing the 2SC4689, placed in the schematic category of the catalogue.

Part-number reference for the 2SC4433 in PDF form, about 71.5 KB. The name gives no board or device, only the JIS designation, where 2SC denotes an NPN bipolar…

Component data for the 2SC5531 NPN bipolar transistor, supplied as a 51.5 KB PDF and catalogued under schematics.

Datasheet-style PDF for the 2SC3988, 114 KB, filed in the schematic category though the name is a plain JIS transistor number.

Reference sheet for the 2SC5411, a PDF of 311 KB catalogued as a schematic. The name gives only the part number.

A 41.3 KB PDF named 2SC5018 with an additional _E suffix that the name does not explain.

Part reference for the 2SC4987, provided as a 110 KB PDF and filed under schematics. No model, board or revision is stated in the name.

A 106 KB PDF for the 2SC3143, which the JIS 2SC designation marks as an NPN bipolar transistor.

Datasheet-style PDF for the 2SA1858 semiconductor, catalogued here under schematics, with an _E suffix in the name that likely marks an alternate edition of the…

A 296 KB PDF identified only by the JEDEC-style part code 2N5769. The catalogue lists it as a schematic, yet the name points to a single discrete semiconductor, so its…

Reference sheet for the 2N4264, saved as a 264 KB PDF and carrying an RE tag in the file name that is not explained further.

The name identifies only the part 1SS377, so this 69.8 KB PDF is best treated as a diode data sheet even though it is indexed as a schematic.

The name 1SS360F gives a small-signal silicon diode number, per the JIS 1SS prefix, followed by an F suffix whose meaning the name does not state.

A small 68.0 KB PDF whose name holds only the component code 1SS337, with no brand, model or board number given.

Nothing beyond the code 1SS309 appears in the name of this 69.5 KB PDF, so no device or board can be tied to it.

A 43.4 KB PDF datasheet covering the 1N5400 diode. Although catalogued as a schematic, it is a part specification sheet, the kind of reference you open when a rectifier…

Covering the 1N5396 diode, this 42.7 KB PDF is a manufacturer datasheet rather than a board schematic, despite its category.

Component datasheet for the 1N4148 small-signal switching diode, catalogued here under the schematic category but in practice a part reference sheet.

Indexed as a schematic, the 104mtkb document is a 159 KB PDF whose name follows a power semiconductor series style with no voltage suffix, device model, board number or…

The file 70mtkb is a 73.3 KB PDF filed as a schematic, and its name provides no brand, model or PCB revision.

Catalogued as a schematic, the 210 KB PDF titled 30HFU appears to be a datasheet for a family of power rectifiers sharing that prefix rather than a circuit diagram, as…

Datasheet-style PDF, 110 KB, carrying the part number 27l2048 and placed in the schematic category.

Very short 20.1 KB PDF for the part 27C256-12A, catalogued as a schematic. The number belongs to the 27C EPROM family, and the -12 suffix normally reflects the…

PDF, 223 KB, named 30CTQ035, which follows the numbering of a discrete semiconductor rather than a board design, pointing to a component datasheet in the schematic…

PDF of 146 KB that groups several part numbers in its name: 24C02, C02R and W02, apparently related 2 Kbit (256-byte) I2C EEPROM variants covered in one datasheet.

Laptop schematic in PDF form for the Z96Jm board at revision 1.0, 1.31 MB, with no brand stated in the name.

Circuit diagram set for the Lenovo ThinkPad E390, delivered as a 1.49 MB PDF. No board number or revision appears in the name, so check the title block inside against…

Samsung F731U schematic, packed as a ZIP of about 3.43 MB; F731U is the US version of the Galaxy Z Flip5. The name carries no revision information.

English PDF on testing electronic components, filed under schematics but in practice a general reference rather than a circuit diagram for a particular board.

Lenovo schematic in PDF for motherboard NM-E211, 2.42 MB. NM-xxxx numbers follow the pattern used by LCFC, the Lenovo affiliated ODM that designs many ThinkPad and…

Schematic in PDF format, 4.02 MB, for the motherboard numbered 203013-1, a pattern typical of Wistron designs; the name gives no laptop brand or model.
