Filed as a schematic, this 52.8 KB PDF covers the 2SB709A, a PNP bipolar transistor in JIS terms, with the A suffix indicating a variant of the 2SB709 that may carry different ratings. The _E tail likely denotes English. It should be a datasheet with package drawing, lead order, limits and gain classification. Check which letter variant is actually fitted on the board, compare voltage and current specifications, and verify the pinout of any substitute, since similar packages can swap emitter and collector.
