PDF of about 228 KB for the 2SA1297 PNP transistor, the 2SA prefix being the Japanese JIS designation for that device class. No board, model or revision is named, so it should be read as a datasheet even though the index lists it as a schematic. Look in it for the pinout, case style and electrical characteristics. It is handy when a transistor tests open or shorted with a meter and you need to know which leg is which, or when cross-referencing an equivalent part for a repair.
