PDF for the 2SC1172, 74.4 KB, listed among schematics with no further detail in its name.

A PDF reference sheet for the 2SD2259 transistor, catalogued as a schematic but in practice a component datasheet of 43.3 KB.

At 312 KB, this PDF for the 2SD2638 is the largest in its series and is probably a full datasheet with curves and outline drawings, though it is filed under schematics.

Reference sheet in PDF form, 141 KB, for the 2SD2198 transistor. The file is indexed as a schematic but is most likely a datasheet.

Small PDF of 92.1 KB filed under schematics, though its name is simply the part number 2SD1998, so it is almost certainly a component datasheet rather than a board…

PDF of 43.6 KB for the 3N252, listed under schematics though the name is a bare JEDEC part number.

Part reference for the 3N250, stored as a PDF of about 43.6 KB and catalogued in the schematic section.
