PDF datasheet for the 2SD2406 transistor, a larger 176 KB file in the schematic category. By JIS numbering, 2SD marks an NPN bipolar device for low-frequency or power duty. The file size suggests characteristic graphs alongside the ratings tables, though the name gives no maker or package. Repairers use such curves and limits to judge whether a replacement can handle the same dissipation. Confirm the pin order against the package drawing before soldering.
