Datasheet-type PDF of 183 KB for the JEDEC part number 2N5758, catalogued here as a schematic.

A 149 KB PDF for the 2N6107, catalogued as a schematic though almost certainly a datasheet, carrying an RE suffix whose meaning is not stated.

A 294 KB PDF for the 2SK209, filed as a schematic. In JIS semiconductor nomenclature the 2SK series is N-channel FETs, so this is effectively a component datasheet.

A 111 KB PDF for the 2SK1453, placed among schematics, although the part-number naming points to a component data sheet.

A 71.5 KB PDF for part 1SV276, held in the schematics category. Going by the 1SV numbering, the component is a variable-capacitance diode and the file a datasheet…

Component sheet for the 2SA1854 in PDF form, about 41.6 KB, placed in the schematic section of the index.

A 130 KB PDF bearing the part number 2N5459, catalogued as a schematic though no board, device or revision is named.

Revision 5 of a datasheet for the 4N25 optocoupler, a 281 KB PDF. The 4N25 is one of the oldest and most common phototransistor-output isolators, often found in power…

Small 40.1 KB PDF for the 2SD1957, written in lower case in the original name and catalogued under schematics.

Compact 16.0 KB PDF datasheet for the 2N3055 from UTC, as indicated in the name, filed in the schematic category.

Indexed as a schematic, a 295 KB PDF labelled 2N6426, from the JEDEC 2N series of discrete semiconductor part numbers.

Revision 3 of a datasheet for the 1N5817, the 20 V part of the 1 A Schottky rectifier family, supplied as a 96.3 KB PDF and filed as a schematic.

Filed in the schematic section, this 156 KB PDF is named for the 2SC4135, which by JIS convention is an NPN bipolar transistor, so expect a component datasheet inside.

Filed as a schematic, this 81.8 KB PDF covers the 2N6520 and carries a Sam tag in brackets, which likely identifies the source or vendor of this edition, though the name…

PDF schematic for an active subwoofer project designated PSW500, a 284 KB document credited to Rat Net, whose name describes it in Spanish as an active subwoofer.

A 53.4 KB PDF for 2N5551, carrying a Sam tag in brackets that likely names the publishing manufacturer, though the abbreviation is not spelled out.

A compact 32.6 KB PDF for the 2N3773, a JEDEC-registered 2N-series transistor; despite the schematic label it is a component datasheet rather than a circuit drawing.

SMD marking code reference in PDF form, 11.4 MB. Books of this type list the short codes printed on surface-mount transistors, diodes, regulators and other small…

Small 20.5 KB PDF named for 2N5551 with a UTC tag, which most likely refers to the manufacturer that published this version.

Schematic for the 60 W NDFL amplifier published by ETI in 1983, combined with a regulated power supply, in a 6.74 MB PDF.

Another copy of documentation for the 2SD1458 NPN transistor, stored as a 48.8 KB PDF under a lowercase file name.

Short 49.9 KB PDF document for the 2N6284, a JEDEC-registered discrete semiconductor, catalogued as a schematic though it is most likely the part's datasheet.

Component datasheet for the 2SD882S transistor as published by UTC (Unisonic Technologies), filed here under schematics although it is a part specification rather than a…

Silicon Chip magazine, November 2005 issue, in PDF form at 15.4 MB; the trailing number in the name suggests a duplicate copy.

ZAWAY resistance map PDF covering pages or models 6 to 7, 23.5 MB; 阻值图 is Chinese for resistance value diagram.
