We use a Nexperia ESD Diode PESD5V0F1BL with a package called SOD882

That is a typical DFN which Library Expert Pro creates as DIODFN98X58X50-2N

Datasheet see Digikey or Nexperia

Due to AOI requirements we must move to the PESD5V0F1BLD what Nexperia calls a DFN1006-2 (SOD882D) package

This component will be soldered at the side too, hence optical inspection possible

But what surface mount type shall i choose to create the footprint?

It is not a Dual Flat No_lead DFN 2 Pin

But it is also not realy a molded body

BTW we often come across this No Lead limitation that prevents us from using the calculator as we have a lead version. would be nice to select Lead / No-Lead.

If i use the manufacturing recommended footprint, then there is no need to use library expert tool.

But:

Manufacture Nexperia recommends a width (W) of 0.7mm whereas Library expert uses only 0.53mm width pads.

So i am asking gain, what would be the way to create a PESD5V0F1BLD DFN1006-2 (SOD882D) footprint with the library expert pro.

both packages and footprints are a bit different.

All of these dimensions are guidelines and not set in stone. They are not a standard, but they are for you to use as a base starting point for you to make the decision of what your actual solder joint goal values should be and what your manufacturing and package tolerances should be. 

All of these things affect the calculation of the resulting pad size. 

Library Expert is a tool that enables you to change any of the values to whatever you want, including the insertion of the mfr. recommended pattern. 

Library Expert allows you to see the Terminal Lead on the resulting pad so that you can make an educated judgement for the best soldering results. 

Library Expert auto-generates the drafting outlines for silkscreen Legend, Assembly, Courtyard Excess, Package Body and Terminal Lead and it adds the Pin 1 polarity marking and the proper reference designators. 

There is no land pattern calculator in the world that will magically calculate every mfr. recommended pattern and the mfr. will only provide the pad size and spacing and not all the other elements that go into a library part.
