Datasheet-style PDF for the 2SD2611, stored in the schematic category at 47.3 KB. The name gives only the part number, so revision and manufacturer are not stated. In the Japanese JIS system, 2SD identifies an NPN bipolar transistor for low-frequency service. A repair technician relies on such a sheet to identify base, collector and emitter, check the case style and compare electrical limits when choosing an equivalent. Open it with any PDF reader and verify the printed marking on the board part before trusting the data.
