Reference sheet for the 2SD1062 transistor in PDF form, about 104 KB, catalogued under schematics. The name gives only the part number, which follows the Japanese JIS convention where 2SD denotes an NPN low-frequency bipolar device. Repairers open it in any PDF viewer to confirm terminal layout, absolute maximum ratings and hFE range, which matters when a failed output or switching stage needs a direct swap or a cross-referenced alternative with at least the same voltage, current and power capability.
