Very small PDF, 29.2 KB, for the JEDEC-registered 2N6076, indexed as a schematic but presumably the part's datasheet, possibly only a page or two. The name gives no manufacturer or revision. The 2N prefix denotes a two-junction semiconductor under the JEDEC scheme. A repair technician consults this kind of sheet to identify leads, look up maximum ratings and the package outline, and decide whether a cross-referenced substitute is suitable for the circuit being fixed.
