Claim:
1. A surface mount device comprising: a casing comprising a first surface, a second surface opposite said first surface, and at least one side surface; a recess formed in said first surface and extending at least partially into said casing; a plurality of leads at least partially encased by said casing, wherein each of said leads comprises a surface mount area at a first end, a device coupling area at a respective opposite end, and an extended lead portion extending between said surface mount area and said device coupling area, wherein said extended lead portion comprises a width less than the width of said surface mount area, wherein at least one of said extended lead portions extends along said at least one side surface, wherein said leads are angled to align said device coupling areas along first and second perpendicular axes, and wherein said device coupling areas are narrower than the widths of said extended lead portions, said device coupling areas straddling said first and second perpendicular axes; one or more electronic or optoelectronic devices coupled with at least one of said device coupling areas, said one or more electronic or optoelectronic devices exposed through said recess; and a heat sink comprising a raised portion and an extended plate and a laterally and circumferentially extending shelf, wherein said raised portion protrudes from said extended plate, wherein said shelf comprises first and second opposing lateral surfaces and a tapered circumferential perimeter connecting the first and second opposing lateral surfaces and tapered toward a central axis of said heat sink, wherein said casing comprises a material that is partially below said extended plate and adjacent to said shelf, wherein at least a portion of each of said leads is in thermal contact with said raised portion, extends up the length and to the top of said raised portion, and is shaped to match the contours of and at least partially frame at least said raised portion, said one or more electronic or optoelectronic devices on a mounting surface of said heat sink, wherein said device coupling areas are proximate to said raised portion of said heat sink.
