The 69.8 KB PDF here is labelled with nothing more than 1SS321, a part number in the Japanese small-signal diode designation used largely by Toshiba.

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.

Catalogued as a schematic, this 129 KB PDF is named after the part number 1SS271, which reads like a component datasheet rather than a board drawing.

A short 64.3 KB PDF titled after the 1KAB-E series, catalogued as a schematic but by its name more likely a datasheet covering a family of discrete components such as…

Marking-code guide in PDF for Micro Commercial Components (MCC), a maker of diodes, transistors, MOSFETs and other discrete semiconductors.

The 2SD2648 is covered by this 29.0 KB PDF, indexed as a schematic but in practice a single-device reference.

Here is a compact 94.6 KB PDF named for the transistor type 2SC4660. The name points to the part itself rather than any board or appliance.

Part documentation for the 2SC5026 in PDF form, 41.3 KB, its name ending in an _E suffix.

PDF document for the 2SC4853, a part number following the Japanese JIS scheme in which the 2SC prefix marks an NPN bipolar transistor.

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…

Only the part number 1SS374 is given in the name of this 68.5 KB PDF, so treat it as a component specification rather than a board 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.

PDF reference listing Ricoh component marking codes, the short codes printed on small SMD packages.

PDF document of 41.7 KB for the 2SC4737, filed in the schematic category but named after a part rather than a board.

Datasheet for the 2SB1658, filed in the index as a schematic but in practice a component data document in PDF form, 48 KB.

Component data for the 2SB1527 in PDF form, roughly 73 KB, catalogued as a schematic though the bare part number suggests a datasheet.

Short PDF of only 19.4 KB covering the 1SV298H, the H suffix marking a variant of the base 1SV298 part.

Part number 1SS181 gives this 70.1 KB PDF its name, and the index places it among schematics.

The file name gives only 1SS348, a part number in the Japanese 1SS small-signal diode series, common in Toshiba catalogues.

Catalogued as a schematic, this 67.4 KB PDF is named for the part 1SS344 and states nothing else about a device or board.

Spanish-language training document on intermediate microelectronics for mobile phones, filed under schematics but by its title a course text rather than a circuit…

A short 87.3 KB PDF for the 1SS403. It sits in the schematic category but reads as a component datasheet, because 1SS is the Japanese designation family for small-signal…

The name 1ss244 indicates a datasheet for a small-signal diode in the Japanese JIS 1SS series, although the file sits in the schematic category.

PDF of 47.7 KB named 2PD602A, apparently issue 4 of the document. The name identifies a part rather than a product or board, which points to a discrete semiconductor…

Listed as a schematic, this 28.7 KB PDF is named only after the part number 2SC5681, which in the Japanese JIS scheme marks an NPN bipolar transistor, so it is most…

Reference sheet in PDF form, 29.3 KB, for the part numbered 2SC5689. Although listed as a schematic, a name made of only a JIS transistor code points to a manufacturer…

Datasheet-style PDF of 101 KB for the 2SA1731, indexed under schematics but named only by part number with no device or board information.

Datasheet-sized PDF, 46 KB, listed as a schematic for the part 2PA1774J, with the trailing 2 most likely a document revision.

Component sheet in PDF format, 47.7 KB, named for 2PC4081, probably revision 4 of the document.

The 1SV266 is the only detail in this file name, and the 59.2 KB PDF is indexed as a schematic.

PDF reference covering voltage regulators in 5-pin, 6-pin and 8-pin packages, catalogued as a schematic.

Datasheet in PDF for the PZT2907A, a PNP small-signal transistor the file name rates at 60 V.

Circuit diagram for the LG G5300 mobile phone, in a 1.02 MB PDF. The file name is partly in Persian and literally means schematic of the LG G5300 phone.

PDF datasheet for the IRFR3806PbF, an N-channel MOSFET rated in the file name at 60 V and 43 A, in the surface-mount DPAK package with lead-free finish.

A second copy of the Dell N5110 schematic, a 1.45 MB PDF with no board or revision data in its name.

Layout map in PDF form labeled Y210-0010; the dash has been garbled into odd characters by an encoding error in the file name.
