A 144 KB PDF whose name is just the part number 2SD1190, filed as a schematic but in practice a transistor datasheet.

Spanish table of SMD equivalences, a cross-reference for surface-mount parts rather than a device schematic. No brand or board is named.

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

Datasheet for the 2N3055, filed here under schematics as a 39.8 KB PDF. The 2N3055 is a classic NPN silicon power transistor, usually in a TO-3 metal can, found in…

A 56.1 KB PDF for the 2N3704, a JEDEC-registered 2N-numbered transistor, indexed as a schematic though it is a part datasheet.

Listed in the schematic category, this 139 KB PDF named 27c020 is in fact best read as a datasheet for a 27C-series CMOS EPROM.

Small 21.1 KB PDF for the 2SC945 transistor, with UTC in the name identifying the Unisonic Technologies version of this widely used small-signal NPN part.

Datasheet PDF for the 2SC5376F, a variant of the 2SC5376 NPN transistor; the trailing F usually indicates a different package or grade, though the name does not explain…

PDF reference for the 2N3820, only 26.3 KB, likely a short one- or two-page data sheet, although the index files it as a schematic.

PDF datasheet of 85.9 KB covering the 1N5221 through 1N5279B zener diodes, indexed under schematics. The B in the range name points to the tolerance grade documented.
