Revision 1.53

14 - 16

Notes:

1. Dimensioning and tolerancing are compliant with ASME Y14.5M-1994.

2. Dimensions are in millimeters, angles in degrees (º).

3. N is the total number of terminals.

4. The terminal 1 identifier and terminal numbering convention shall conform to JESD 95-1 SPP-012. Details of

terminal 1 identifier are optional, but must be located within the zone indicated. The terminal 1 identifier may

be either a mold, embedded metal or mark feature.

5. Dimension b applies to metallized terminal and is measured between 0.15 and 0.30mm from terminal tip.

6. ND refers to the maximum number of terminals on D side.

7. Variation shown in Figure 18 is for illustration purposes only.

8. For variation identifier dimension details, refer to the Dimensions table.

9. For a complete set of dimensions for each variation, refer to the Variations table.

10. Unilateral coplanarity zone applies to the exposed heat sink slug and the terminals.

11. For a rectangular package, the terminal side of the package is determined by:

- Type 1: Terminals are on the short side of the package.

- Type 2: Terminals are on the long side of the package.

12. Variations specified as NJR (non JEDEC registered), with an additional dash number (e.g., -1, -2) are pack-

ages currently not registered with JEDEC.

13. When more than one variations exist for the same profile height, body size (DxE), and pitch, then those vari-

ations will be denoted by an additional dash number (i.e., -1,-2) for identification. The new variations shall be

created based on any or all of the following factors: terminal count, terminal length, and exposed pad sizes.
