Notes
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
3. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction.
4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm;
5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
