Combined PDF, 53.0 KB, whose name lists two part numbers, 2SB1189 and 2SB1238, suggesting one data sheet covering both transistors. It is filed as a schematic. Under the JIS system the 2SB prefix designates PNP transistors originally classed for low-frequency use. Shared sheets often cover parts with similar dies in different packages, so check which outline applies. Use it to read pinout and ratings, compare the two variants, and pick a valid substitute when the original fails.
