A 30.8 KB PDF named for the 2SA1522, a part number in the Japanese 2SA series of PNP transistors. Although the index lists it as a schematic, the name points to a component data sheet rather than a board diagram. Expect electrical characteristics, maximum ratings and a package outline. Open it in any PDF reader. Repair work typically relies on such a sheet to find a valid substitute, confirm emitter, base and collector positions, and judge whether measured readings indicate a damaged junction.
