Transistor reference for the 2SC3325 in a 196 KB PDF, catalogued as a schematic but most probably a datasheet.

A 191 KB PDF describing the 2SC4604 transistor, categorised as a schematic though its content is almost certainly a manufacturer datasheet.

Reference PDF for the 2SA1923 transistor, 195 KB, catalogued as a schematic though nothing in the name beyond the part number indicates more than a datasheet.

Carrying only the code 112cnq030a, this 193 KB PDF is catalogued as a schematic yet mentions no laptop, board number or revision.

Indexed under schematics, the 197 KB PDF for the 2SC5460 is most probably a full datasheet for this NPN transistor from the Japanese 2SC series.

The 2SB1457 is covered by this 192 KB PDF, the largest of the group, filed as a schematic but named like a standard component datasheet.

The 2SA1621 is covered by this 194 KB PDF, listed among schematics but really describing one discrete semiconductor.

PDF documentation, 195 KB, for the 2SB907. Japanese JIS numbering assigns the 2SB prefix to PNP transistors meant for low-frequency applications.

A 193 KB PDF for the 2SA950, catalogued as a schematic but carrying a JIS semiconductor designation.

Filed under schematics, this 191 KB PDF refers to the 2SD1223 transistor. In Japanese JIS numbering, the 2SD prefix identifies an NPN bipolar device for low-frequency…

A 196 KB PDF named for the 2SC4684 and listed in the schematic category. Its 2SC prefix is the JIS marker for NPN bipolar transistors, so the document is best read as a…

For the 2SC5439 transistor, this 192 KB PDF is most likely a manufacturer datasheet, given that 2SC is the JIS designation for NPN bipolar parts.

Component documentation for the 2SC3669 in PDF format, 192 KB in size. The 2SC prefix in Japanese JIS numbering indicates an NPN bipolar transistor, and the bare…

Datasheet-type PDF, 195 KB, for the transistor 2SA1971, whose 2SA prefix marks a PNP bipolar device under the Japanese JIS scheme.

Datasheet PDF of 190 KB for the 2SA1761, filed under the schematic type. In the JIS scheme the 2SA prefix denotes a PNP bipolar transistor, and the name gives nothing…

This 193 KB PDF, catalogued under schematics, is named 110cnq045a, which reads as a discrete power component code rather than a board identifier.

A 199 KB PDF for the 8ETH03 part, listed as a schematic in the index. The name fits the International Rectifier and Vishay hyperfast rectifier coding, so expect a…

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

2SC5154 is the only detail in this 198 KB PDF name, and that JIS designation points to an NPN bipolar transistor of the high-frequency group, so treat the file as a…

A 195 KB PDF labelled with the transistor type 2SC4210. No device, board or manufacturer is named; the 2SC prefix simply tells us, through the Japanese JEITA system…

Datasheet-type PDF of 197 KB for the 2SA2069 transistor, indexed under schematics. Following JIS naming, the 2SA prefix identifies a PNP transistor intended for…

Part-number document for 2SA2056, stored as a 191 KB PDF and listed in the schematic section.

Component sheet for the 2SA1925 in a 198 KB PDF, labeled as a schematic though the plain part-number name suggests a manufacturer datasheet.

A 19.2 KB PDF for part number 1SV294, classified here as a schematic. The 1SV family generally consists of varactor diodes, so the document should describe one discrete…

Identified only as 115cnq015a, this 193 KB PDF sits in the schematic category with no board number, revision or product mentioned.

Named 20ETF-FP, this 198 KB PDF sits in the schematic category but states no laptop brand, board number or revision.

PDF schematic for the Compal LA-A972P laptop motherboard, 1.19 MB. The file name gives only the board identifier, so brand, model and revision are not stated.

Yamaha PA 2400 amplifier schematic in a small 194 KB PDF. The name gives no revision or note about modifications, so it may represent the standard circuit, but confirm…

Circuit diagram for a power adapter labelled DAG-3004, packed in a small 194 KB RAR archive. The name gives no brand or output rating, so check the label on the brick.

Toshiba Portege R830 schematic in a sizeable 19.9 MB PDF. The file name carries no board number or revision, so open it and compare the project and board markings with…

Samsung laptop schematic for the Praha platform, SRI variant, revision 1.0, provided as a 1.19 MB PDF.
