Is it ok to connect NC pads to either of Drain, Source terminals? In the layout, due to the NC pins being adjacent to the Drain pins, the drain copper pour is shaped weirdly and this limits the number of vias I can place on it.
Connecting NC pads with Drain would give me a nice rectangular pour which will make routing easier and more vias can be added for higher current capability.
Also, will connecting NC pads with Drain/Source cause emissions? Or affect the package working internally?

Hello,
Thank you for posting on Infineon Community.
The NC pads of the package are not connected to the die inside the package.
You can refer to chapter 1.5 of the following app note:

Example:
Therefore, the drain pads can be connected to the NC pads.
Source pads however, should not be connected to the NC pads, as this creates creepage issues.
Best regards,
Pablo
