SMD catalog in PDF form, 3.04 MB, listed under schematics but by its name a reference for surface-mount components rather than a circuit for a particular device.

SMD Databook 2011 covering active SMD semiconductor components, a 19 MB PDF reference catalogued under schematics.

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

Small 25.5 KB PDF for the 2SA1816, bearing an _E suffix in its name and catalogued as a schematic. Under JIS rules the 2SA prefix marks a PNP bipolar transistor.

Catalogued as a schematic, this 184 KB PDF is named only after the part number 2SC5175, so it is most likely the manufacturer datasheet for that discrete transistor.

A 52.6 KB PDF for the 2SC3933, labelled with an _E suffix and catalogued as a schematic.

PDF file of 70.1 KB for the 1SV279 part, catalogued as a schematic. The 1SV designation belongs to varactor diodes, so the document should present one component…

Catalogued as a schematic, the 44.6 KB PDF 2SA1973 is named after a JIS-numbered PNP bipolar transistor, identified by the 2SA prefix.

A 155 KB PDF for the 2SC5245 transistor, catalogued as a schematic but by its name almost certainly a component datasheet.

Named 2SC5069 and weighing 107 KB, this PDF is catalogued under schematics but represents a JIS-numbered NPN bipolar transistor, so treat it as a datasheet.

A 41.5 KB PDF covering the 2SC4808, a part number in the JIS 2SC series used for NPN bipolar transistors.

Here the 41.7 KB PDF is labelled with the part number 2SA2023, a PNP bipolar transistor under the Japanese JIS 2SA designation.

Datasheet-style PDF of 41.8 KB covering the 2SA1790, a JIS-coded PNP bipolar transistor, placed in the schematic section of the catalogue.

Part number 1SV241 names this 62.8 KB PDF, catalogued as a schematic, with no revision or variant noted.

PDF file for the 1SS388 part, 68.6 KB, catalogued under schematics though most likely a single-component datasheet.

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.

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

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

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.

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