Filed as a schematic, a 21.2 KB PDF for the 2N6517 bearing a Sam marker in parentheses, probably denoting the publishing source of this particular edition, which the name leaves unclear. As a JEDEC 2N part number, the document is expected to be a datasheet giving maximum ratings, pinout and package dimensions. Since second-source makers sometimes differ in limits or case style, compare it with the other 2N6517 sheet before ordering a replacement or checking a suspected failed component.
