Revision 1.4

13 - 16

Notes:

1. Dimensioning and tolerancing conform to ASME Y14.5M-1994.

2. All dimensions are in millimeters; angles in degrees.

3. N is the total number of terminals.

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

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

a mold or marked feature.

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

of the terminal has the optional radius, the b dimension should not be measured in that radius area.

6. Dimensions ND and NE refer to the number of terminals on each D and E side, respectively.

7. Depopulation is possible in a symmetrical fashion.

8. Figure 19 is shown for illustration only and does not represent any specific variation.

9. All variations may be constructed per Figure 19, however variations may alternately be constructed between square

or rectangle shape per dimensions D and E.

10. Refer to the Dimensions Table for a complete set of dimensions.

11. Bilateral coplanarity zone applies to the exposed heat sink slug as well as the terminals.

12. Depending on the method of lead termination at the edge of the package, pullback (L1) may be present. L minus

L1 to be

≥ 0.33mm.

13. For variations with more than one lead count for a given body size and terminal pitch, each lead count for that vari-

ation is denoted by a dash number (e.g., -1 or -2).

14. NJR designates non-JEDEC registered package.
