Reference sheet for the 2SB1015A, a 167 KB PDF placed in the schematic section. The Japanese JIS 2SB code designates a PNP bipolar transistor for low-frequency applications, and an A suffix commonly identifies an upgraded variant. The document should help a technician read pinout, collector-emitter breakdown voltage, collector current, dissipation and gain. Use it to test the part out of circuit, confirm its marking, and choose a replacement; verify the suffix because base and A versions may not be interchangeable.
