Boardview for the Dell XPS L502X, covering motherboard DAGM6BMB8F0, with DAGM6TB48B0 also listed, likely a related secondary board.

Small RAR archive for the ASUS X550VX laptop holding an .asc file. In ASUS repair sets that extension normally belongs to a boardview-type layout, readable in viewers…

PDF schematic named T60PM, a ThinkPad T60 drawing where PM most likely indicates the Intel 945PM chipset version used with discrete graphics; the name gives no revision.

Second PDF copy of the Quanta AT5 motherboard schematic, revision R1A, about 1.22 MB. AT5 follows the project-code pattern of Quanta, the ODM that manufactures laptops…

4N29 datasheet in PDF, describing a photodarlington optocoupler in six-pin DIP that offers higher current transfer ratio than plain phototransistor types such as the…

PDF schematic covering the SM7225 processor, 1.52 MB, with no handset model or revision mentioned. Open it in a PDF reader to search net names and pin functions.

Schematic in PDF, 1.68 MB, for the SM6125 processor with an SM61 family tag; the phone model and board number are absent from the name.

Schematic archive catalogued under Samsung and named only A12, presumably the Galaxy A12 handset, though the name does not confirm the variant.

Schematic archive named only M33, with no brand given, a 940 KB ZIP. The name is too brief to identify the device reliably; it may be a phone model code, but that is not…

Boardview for the HP 14-BP laptop, Quanta G72D platform with board number DAG72DMB6D0. The DA-prefixed code follows Quanta numbering, where the platform letters sit…

PDF reference for the 2SD1852, a 2SD-series NPN bipolar transistor, about 96.5 KB and more likely a component datasheet than a circuit diagram.

Datasheet for the 4N38 optocoupler, marked as revision 2 in the name and supplied as a 294 KB PDF filed among schematics.

Revision 5 of a datasheet for the 4N25 optocoupler, a 281 KB PDF. The 4N25 is one of the oldest and most common phototransistor-output isolators, often found in power…

Indexed as a schematic, the 2SD1723 PDF of 146 KB is a component sheet for one discrete transistor.

Datasheet-style document, 133 KB in PDF format, covering the 2SD1681 part number and listed as a schematic.

PDF reference, 67.1 KB, for the 2SD1627 transistor, stored in the schematic section. The name carries nothing besides the part number.

Reference sheet in PDF form (32.2 KB) for the 2SK3414LS, listed in the schematic section of the index.

Filed under schematics, this 413 KB PDF is named after the 2SK2838. The 2SK prefix in the JIS system indicates an N-channel FET, so the file most likely holds the…

A 429 KB PDF titled 2SK2789 and stored among schematics, most likely the datasheet for that part.

Part documentation for the 2SK2731, a 113 KB PDF placed in the schematic category. JIS naming assigns the 2SK prefix to N-channel field-effect transistors, so the…

Small 23.4 KB PDF for the 2SK2660 transistor. The 2SK designation comes from the Japanese JIS system for N-channel FETs, so the file is most likely a brief datasheet…

A 322 KB PDF datasheet for the 2SK2613, indexed under schematics. The 2SK prefix is the Japanese JIS registration for N-channel FETs, and the file size points to a…

A 166 KB PDF covering the 2SK1961 transistor. The 2SK series in the JIS system denotes N-channel FETs, so this schematic-categorised file should be read as a component…
