Component documentation for the 3N246, a 43.6 KB PDF indexed as a schematic. The name follows the JEDEC 3N numbering used for four-terminal semiconductor devices, and the identical size to adjacent part numbers hints that it belongs to a shared family datasheet. Useful for confirming lead assignment, maximum voltage and current values, and package dimensions during a repair. Any PDF reader will display it; check which variant within the family your board actually carries before relying on the figures.
