The 2SC1359 named in this 55.6 KB PDF is, by its 2SC prefix, a Japanese-standard NPN bipolar transistor, so despite the schematic label the document should be a…

Component datasheet for the 2SB1434 transistor, filed under schematics but in practice a part reference rather than a board diagram.

PDF document for the 2SA1635, filed under schematics but in fact a component sheet for a discrete transistor; the _1-2 suffix in the name likely marks a part or revision…

A PDF document for the 2SA1604, an 84 KB file listed in the index as a schematic but named after a single discrete part rather than a board.

An 80.4 KB PDF covering the 2sb1260 transistor, listed in the index under schematics. No maker, package or device model is given in the name.

Component sheet for the 2SA1723, an 80.1 KB PDF. The name holds only the part number, so no equipment model or board revision can be attached to it.

PDF of 34.7 KB for the 2SA821S, one of the smallest documents in this group, with only the part number in its name.

Very small PDF, only 16.5 KB, named 2pg352 and catalogued under schematics. The name is terse and gives no device, brand or board number, so it most likely holds a one…

Small PDF of 46.9 KB filed as a schematic and named for 2N1711, a JEDEC-numbered discrete semiconductor designation.

Covering the 1N746A to 1N759A range, this 74.3 KB PDF is a family datasheet for a series of JEDEC zener diodes, although the index files it as a schematic.

Here is the 1N5398 diode specification sheet in PDF form, 42.7 KB, indexed as a schematic.

At 377 KB this is the largest of a group of PDFs named after 1N part codes; this one is 1N1183, a JEDEC style diode designation, so it is most probably a datasheet even…

This 124 KB PDF is named with the code 5TUZ52 and listed as a schematic, though no device, board number or revision is stated.

Catalogued as a schematic, the 1SR139 document comes as a 117 KB PDF whose name mentions 400 and 600 variants, so it likely covers two grades of one discrete part.

Here is a 323 KB PDF named for the 25AA040, 25LC040 and 25C040, a Microchip family of 4 Kbit SPI serial EEPROMs; despite the schematic label it is a datasheet.

Datasheet-style PDF of 55.8 KB for the Catalyst 24WC256, a 256 Kbit two-wire serial EEPROM, even though the index lists it as a schematic.

A 75.1 KB PDF titled after the 24C16 part, with a _3 suffix that likely marks a third copy or revision of the same reference sheet.

A compact 44.5 KB PDF named 20FQ appears in the schematic category with no device or board information in its name.

Schematic PDF of 328 KB whose name, 8CLJQ045, reads like a component or part code and gives no laptop model, brand or board number.

Compressed RAR containing a PDF schematic for the N76VM, tagged RG as on similar ASUS schematic packages; no board revision appears in the name.

PDF reference on the CPU power sequence for Intel Broadwell-ULT processors, 1.66 MB. It is catalogued as a schematic but likely shows the order of rails, enables and…

Circuit schematic for the IBM ThinkPad R32, provided as a 1.18 MB PDF. The name mentions no board number or revision, so check the motherboard silkscreen against the…

PDF schematic of about 1004 KB for a motherboard labeled F83VF, with the r11 token most likely pointing to revision 1.1.

Inventec schematic for the 15SBGV2 / 15SBGV2D mainboard, part number 6050A2548101, built on the Intel Shark Bay platform with a PGA processor socket and labelled PV…
