A 28.0 KB PDF classed as a schematic whose name, 3LP01C, reads as a component part code ending in C. The file name gives no device, board number or manufacturer.

Named only 2sd1897, this 35.6 KB PDF is listed as a schematic, yet the name is a JIS transistor number, so it is very likely a compact datasheet.

A 30.6 KB PDF labelled with the JIS part number 2SK3488 and filed in the schematic category, though the content should be a component datasheet.

Brief 28.4 KB PDF for the 2SK2864, indexed as a schematic; its small size points to a one or two page datasheet or summary. The name gives only the part number.

A very small PDF of 23.8 KB named for the 2SK2797, filed under schematics. The 2SK prefix follows the JIS naming convention for N-channel field-effect transistors, so…

Short PDF, 43.6 KB, named after the 2SK2791 and listed as a schematic. The 2SK prefix marks an N-channel FET under the JIS scheme, so this is likely a compact datasheet.

PDF reference, 35.6 KB, for the 2SK2276, a Japanese JIS-registered device where the 2SK prefix indicates an N-channel field-effect transistor.

Only the transistor number 2SJ259 appears in the name of this 99.0 KB PDF. JIS coding uses 2SJ for P-channel FETs, which suggests a datasheet even though the file is…

PDF document for the 2SD1205 transistor, listed in the index as a schematic but almost certainly a part datasheet; the trailing _E in the name is a suffix whose meaning…

Part number 2SC3805 is the only information in this 184 KB PDF name, and although it is listed as a schematic, the 2SC prefix under Japanese JIS numbering identifies an…

The 2SC3747 transistor is covered by this 95.9 KB PDF, categorised as a schematic but by its name a datasheet for a single component.

Specification sheet for the 2SC3600 transistor in PDF form, 136 KB, listed under schematics.

2SC3598 datasheet in a 119 KB PDF, catalogued in the schematic group. Only the part number appears in the name; under Japanese JIS numbering the 2SC prefix identifies an…

A 58.1 KB PDF labelled as a schematic and named after the 2SC1215, an NPN transistor by Japanese JIS naming, so it should be the datasheet for that discrete part.

Component documentation for the 2SA1591, an 89.4 KB PDF. Only the part number appears in the name; no revision or manufacturer is given.

The 2SA1518 is the subject of this 30.2 KB PDF, which the index files as a schematic although the name suggests a component data sheet.

Short 31.2 KB PDF for the 2SA1864, a PNP bipolar transistor in the Japanese JIS 2SA family.

Small PDF listed as a schematic, though the name 2SA777 with suffix E reads like a discrete semiconductor part number in the Japanese 2SA style rather than a board…

A 52.2 KB PDF in the schematic listing, labelled simply 2N6487, a part number from the JEDEC 2N discrete semiconductor series.

The 1SS190 is the only information in this file name, apart from an underscore. The 68.1 KB PDF sits under the schematic category.

Labelled 1SS268, this 126 KB PDF appears to be a datasheet for a single component even though the index lists it as a schematic.

Part number 1SS196 gives this 68.1 KB PDF its name, which marks it as a datasheet for a single semiconductor rather than a full circuit diagram.

A 42.7 KB PDF datasheet for the 1N5391 diode, listed here as a schematic although it covers a single component.

PDF datasheet, 45.5 KB, for the 1N4934 fast recovery rectifier diode from the 1N4933 to 1N4937 family.

PDF datasheet of about 42 KB for the 1N4531, a small signal switching diode. The name carries no other details, so the vendor and document revision can only be read from…

Two part numbers appear in the name, 1N914 and 1N916, so this 78.8 KB PDF is a shared datasheet for two related JEDEC 1N diodes rather than a board schematic.

Datasheet in PDF for the 93C85A, a member of the 93-series Microwire serial EEPROM family, filed here under schematics.

Very small at 30.8 KB, this PDF is labelled only 92R195 and catalogued as a schematic, but the name gives no device, manufacturer or context, so its exact content cannot…

Named 35scgq045, this 70.6 KB PDF is grouped with schematics, but the name suggests a discrete component code and carries no device, brand or revision information.

Reference PDF of 76.4 KB, indexed as a schematic but named only after the part code 30CLJQ150.

Schematic PDF, 2.13 MB, labelled only V6J. The short code looks like a model or project designation, but the name gives no brand, board number or revision.

Schematic in PDF for the IBM ThinkPad T61, about 2.21 MB. The name states no board number, revision or graphics option, and T61 boards were made in integrated and…

Portuguese PDF, 88.3 KB, on using a bench power supply (fonte de bancada), apparently converted from another document format. No device or model is referenced.

Schematic diagram for the Motorola XT1802, delivered as a 3.40 MB PDF. A phone schematic lets a technician follow power rails from the PMIC, trace charging, USB, display…

Spanish reference on SMD coils or inductors, a 273 KB PDF covering surface-mount types found on modern boards. The name gives no device.

Depth camera schematic for the Samsung SM-A21s covering the 2MP depth sensor, PDF format, 3.82 MB.

Touchscreen circuit pages from the Samsung SM-A11 schematic, delivered as a PDF of 4.33 MB.

Schematic PDF with an uninformative name, IO, which suggests an input/output or daughter board but states no device, brand or board number.

Circuit diagram for the Quanta ZC3 laptop mainboard, a 1.59 MB PDF that opens in any PDF reader.

Schematic archive for the Xiaomi Mi 11 Ultra smartphone, packed as ZIP at about 3.6 MB.
