Component reference for the 2SD2568, a 44.6 KB PDF in the schematic category. The 2SD prefix follows JIS numbering for NPN bipolar transistors used in low-frequency circuits, so datasheet content is expected. Nothing beyond the part number is given in the name, so maker and package remain unconfirmed. Use the sheet to identify leads before testing with a multimeter, review collector current and voltage limits, and confirm the board marking matches before ordering a replacement.
