Short PDF document, 47.9 KB, whose name points to the component 2PB710A, with the suffix 6 likely indicating a revision of the sheet. Although catalogued as a schematic, the naming fits a discrete semiconductor data sheet more than a circuit diagram. Repair technicians rely on such documents to read pin order, maximum voltage and current, gain grouping and package dimensions when hunting for an equivalent part. Check the marking code on the faulty device against the sheet before ordering a replacement; the file opens in any PDF reader.
