Datasheet for the 2N3392 in a 296 KB PDF, filed as a schematic. Identical in size to neighbouring 2N3390 to 2N3393 entries, it is probably a shared family document, though the name states only this one number. Repair technicians use it to read gain grouping, ratings and package outline of the 2N-series transistor before replacement or when testing with a meter. Any PDF viewer opens it; pick out the values that apply specifically to 2N3392 from the family tables.
