Small 39.9 KB PDF for the 2SD2474, carrying an _E suffix whose meaning the name does not state; it may reflect a language or edition marker.

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 covering the 3SK189, about 178 KB in size and listed in the schematic category, though the name points to a single component datasheet.

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

A 111 KB PDF for the 2SD2281, which under the Japanese JIS system is an NPN transistor from the low-frequency 2SD series.

A 365 KB PDF for the 2SK2859, filed under the schematic type though it is most probably a manufacturer datasheet. Nothing other than the part number appears in the name.

A compact 134 KB PDF titled with the part number 2SK2839 and catalogued as a schematic.

Short datasheet-type PDF of 30.0 KB for the 2sk2588, an N-channel FET according to the JIS 2SK prefix.
