Combined datasheet covering both the 2N2905A and 2N2907A PNP transistors in one 726 KB PDF, filed under schematics. The larger size suggests a fuller document with characteristic curves, package drawings and test conditions. The A suffix versions carry tighter or higher ratings than the plain types, so the sheet is useful when deciding whether a basic part can replace an A grade or vice versa. Keep in mind the two types usually differ in package, so match the outline and pin order with the board before fitting.
