Listed under schematics, this 52.8 KB PDF refers to the 2SB1675, a PNP transistor in the Japanese JIS numbering system, so its content should be the part datasheet. Sizes and naming closely match neighbouring 2SB167x files, suggesting the same source series. Expect pinout, package drawing, maximum collector voltage and current, dissipation and hFE ranking. Before substituting, check that the replacement is PNP, meets every rating and uses the same pin order, since datasheets for similar cases can differ.
