Notes:
1. Dimension and tolerancing per ASME Y14.5M-1994.
2. Dimension in Millimeters.
3. Dimension D does not include mold flash, protrusion or gate burrs. Mold flash, protrusions or gate burrs
shall not exceed 0.25mm per end. Dimension E1 does not include interlead flash or protrusion. Interlead
flash or protrusion shall not exceed 0.25mm per side. D and E1 dimensions are determined at datum H.
4. The package top may be smaller than the package bottom. Dimensions D and E1 are determined at the
outermost extremes of the plastic body exclusive of mold flash, tie bar burrs, gate burrs and interlead
flash, but including any mismatch between the top and bottom of the plastic body. D and E1 dimensions
are determined at datum H.
5. Datums A & B to be determined at datum H.
6. Package variation “AA” is a 5 lead version of the 6 lead variation “AB” where lead #5 removed from the
6 lead “AB” variation.
7. These dimensions apply to the flat section of the lead between 0.08mm and 0.15mm from the lead tip.
8. Dimension “b” does not include dambar protrusion. Allowable dambar protrusion shall be 0.08mm total
in exceed of the “b” dimension at maximum material condition. The dambar cannot be located on the
lower radius of the foot. Minimum space between protrusion and an adjacent lead shall not be less than
0.07mm.
9. Details of the pin 1 identifier are optional, but must be located within the zone indicated.
