Named 2sa2007, this 52.4 KB PDF relates to a PNP bipolar transistor, as the JIS 2SA prefix indicates. The content is probably a manufacturer datasheet, although the catalogue category says schematic and the name does not state the maker or package. For repair, the pinout and ratings tables let you test the part in or out of circuit and decide whether a replacement with equal or better voltage, current and dissipation limits will fit the same pads.
