A compact 43.5 KB PDF filed under schematics and named for the 2N6547, a part number from the JEDEC 2N registration series for discrete semiconductors. Despite the category, a name like this usually points to a manufacturer datasheet listing ratings, package dimensions and pin assignment. It helps when sourcing a substitute, identifying leads on a board, or judging whether a failed device was run beyond its limits. Compare it with the larger RE-marked version of the same number if details differ between makers.
