The 2SD1879 is documented in this 94.5 KB PDF, indexed as a schematic yet most likely a manufacturer datasheet for the part.

A 41.8 KB PDF named for the 2SD2457 with an E tag, filed as a schematic. By the JIS scheme, 2SD marks an NPN bipolar transistor, so expect a component reference rather…

This 91.1 KB PDF covers the 2SD1887 transistor; it sits in the schematic category but the file name matches a JIS component designation, pointing to a datasheet.

Only 28.2 KB, this PDF named 2sk123 is catalogued as a schematic, but the name is a JIS transistor number, so a short datasheet is the likely content.

Documentation for the 2SK2855, a 125 KB PDF catalogued as a schematic, with no details in the name besides the part number.

Named for the 2SK2824 transistor, this 305 KB PDF is indexed as a schematic but is most likely a single-part datasheet.
