The 2SC5459 comes as a 186 KB PDF in the schematic category, though the part number, a JIS 2SC NPN transistor, points to a datasheet.

For the 2SC5450 there is a 41.0 KB PDF, filed as a schematic, most likely holding the datasheet of this NPN transistor from the Japanese 2SC family.

Part number 2SC2510 gives this 165 KB PDF its name. In JIS numbering the 2SC prefix belongs to NPN bipolar transistors, so the content is most likely the device…

A 359 KB PDF named for the 2SC2498, a transistor designated under the JIS scheme, where 2SC identifies NPN devices.

Small 37.7 KB PDF for the 2SB1308, catalogued among schematics though it documents a single discrete part.

The 2SA1934 is documented in this 237 KB PDF, filed under schematics although the name carries only a component code.

An 87.4 KB PDF describing the 2SA1839 transistor, indexed with the schematic files. Following JIS numbering, the 2SA designation indicates a PNP bipolar transistor.

Shared PDF covering the 2N4400 and 2N4401, 48.6 KB, sorted into the schematic category but most likely a combined manufacturer datasheet.
