Documentation for the 2SD1802 in a 150 KB PDF, filed as a schematic though the name suggests a transistor datasheet.

PDF of about 41.4 KB covering the 5LN01S, catalogued as a schematic but most likely a component datasheet.

PDF datasheet for the 4N35 optocoupler, marked as revision 2 in the file name and about 276 KB in size.

A 167 KB PDF identified only by the 2SD2481 part number, which points to the datasheet for that transistor rather than a board schematic.

Filed as a schematic, this 44.1 KB PDF carries the name 2SD1450 with an _E suffix that the name does not explain; the part number points to a datasheet.

The 3N253 is documented in this 42.2 KB PDF, categorised as a schematic but evidently a discrete-component datasheet.

At 180 KB, this PDF named 2SD2449 is larger than most of its neighbours and is catalogued as a schematic.
