PDF file, 105 KB, for the 2SD2199, placed under the schematic category although the name indicates a discrete transistor datasheet. By JIS convention, 2SD denotes an NPN bipolar transistor for low-frequency applications. Consult the sheet for pin assignment, maximum ratings, saturation voltage and hFE classification when diagnosing an output or switching stage. Before substituting, compare the case outline and body marking with the part on the board.
