Small 39.6 KB PDF containing the datasheet for the 2sb1616, catalogued as a schematic entry. The 2SB label, from the JIS standard, indicates a PNP bipolar transistor for low-frequency use; nothing about manufacturer or package appears in the name. Open it in any PDF reader to look up lead assignment, maximum collector-emitter voltage, collector current and hFE grades. This helps when measuring a removed part, identifying a burnt device by its code, or verifying that a proposed substitute has equal or better ratings.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cyberlanelectonik. Enginerys does not host this file.
