Compact 42.5 KB PDF for the 2SD1824, carrying an E suffix in the name that is not otherwise explained. It is catalogued as a schematic but is likely a datasheet for this JIS-numbered NPN bipolar transistor, the 2SD prefix meaning a low-frequency type. Refer to it for pin assignment, package, breakdown voltage, current limit and gain class. Before ordering a replacement, check that the marking and case style on the original part agree with the sheet.
