Compact 39.6 KB PDF for the 2SD2359, catalogued among schematics but by its name a transistor datasheet. Within the JIS system, 2SD marks an NPN bipolar transistor for low-frequency circuits. The E suffix in the name is not explained. Expect a ratings table, gain data and the package outline. Those help a repairer confirm pin assignment, run junction checks with a meter and make sure a replacement matches the original's voltage and current specification.
