ABSTRACT:
Disclosed herewith is a single in-line type semiconductor device having external leads drawn out from a package in staggered fashion. According to the single in-line type semiconductor device of this invention, a narrow portion to be fitted in an opening formed in a printed circuit board is provided at each of first and second external leads, with the remaining portion of each external lead constituting a wide portion. The first and second external leads are each provided with a positioning portion defined by the narrow and wide portions. The linear distance between one edge portion of the package and the positioning portion of each first external lead is equal to the linear distance between the edge portion of the package and the positioning portion of each second external lead.
