The 2SD2624 is described in this small PDF of 30.0 KB, indexed under schematics, though a part number like this generally indicates a datasheet.

PDF for the 2SD2618, 46.6 KB, with a lowercase name and filed as a schematic. In practice, it should be a datasheet for this JIS-numbered NPN bipolar transistor, as the…

Datasheet-type PDF for the 2SD2616, 45.9 KB, listed under schematics in the index. The JIS code 2SD marks an NPN bipolar transistor meant for low-frequency circuits.

Part documentation for the 2SD2615, filed under schematics but by its name a component datasheet rather than a board drawing.

A 53.4 KB PDF covering the 2SD2614 transistor, catalogued as a schematic although the name points to a single-part datasheet.

Datasheet-style PDF for the 2SD2611, stored in the schematic category at 47.3 KB. The name gives only the part number, so revision and manufacturer are not stated.

Reference sheet for the 2SD2607 component, delivered as a 51.7 KB PDF and filed under schematics. No brand or variant appears in the name beyond the part number itself.

A 194 KB PDF describing the 2SD2604A, listed as a schematic but most likely a transistor datasheet.
