Reference PDF for the 2SD1065, 119 KB, filed in the schematic category although the name identifies a single transistor and points to a datasheet. The 2SD prefix, under Japanese JIS numbering, denotes an NPN bipolar transistor for low-frequency work. The sheet helps a technician identify leads, read breakdown voltages, collector current and dissipation, and confirm the package. Check these details before soldering in an equivalent, and verify the original is faulty before removing it.
