A 103 KB PDF covering the 2SD1063, filed as a schematic although the name points to a single semiconductor rather than a device. In JIS part numbering, 2SD identifies an NPN transistor of the low-frequency class. The document is most useful at the bench for checking package outline and pin assignment, reading collector-emitter voltage and current ratings, and comparing gain figures when hunting for an equivalent. Verify the marking on the actual part matches before relying on the data.
