Notes:

7. The suggested land pattern dimensions have been provided for reference only, as actual pad layouts may vary depending on application. These

dimensions may be modified based on user equipment capability or fabrication criteria. A more robust pattern may be desired for wave soldering and is

calculated by adding 0.2 mm to the ‘Z’ dimension. For further information, please reference document IPC-7351A, Naming Convention for Standard SMT

Land Patterns, and for International grid details, please see document IEC, Publication 97.

8. For high voltage applications, the appropriate industry sector guidelines should be considered with regards to creepage and clearance distances

between device Terminals and PCB tracking.
