The 2N6035 is documented in this 244 KB PDF, indexed as a schematic though it is most likely a datasheet, and tagged with an unexplained RE suffix.

PDF schematic for Quanta board DAG7ALMB8C0, revision C, labelled G7AL-2G, which likely indicates a version with 2 GB of graphics memory.

Schematic for the Samsung Galaxy Core 2, model SM-G355H, stored as a compact 3.20 MB RAR archive.

PDF schematic labelled AM9 MB, apparently a mainboard design with a D revision marker and a date code of 22 June 2015 in the name.

The 2SD2337 is the part this 41.0 KB PDF documents, and as a 2SD number under JIS rules it is an NPN transistor aimed at low-frequency circuits.

Schematic for the Samsung Torino 2 platform covering mainboards BA41-00727A and BA41-00728A, MP 1.0 dated 2009-03-09, labelled Q46, provided as a PDF in a RAR archive.
