PDF for the 2SC5548A, an A-suffix variant of the 2SC5548 NPN transistor, 231 KB and indexed as a schematic.

Documentation for the 2SC5548 NPN bipolar transistor, a 231 KB PDF catalogued under schematics, with a separate 2SC5548A variant also present in the collection.

PDF of 208 KB covering the 2SC5550, listed in the index under schematics but by its JIS part code an NPN bipolar transistor, so treat it as a component datasheet.
