Very nice!

Just two ideas:

• Could the symbols be slightly shrinked to get the pins located on a 4x4 grid instead of 6x6? I think it would help to keep schematics compact. Note that the pin length could be shortened a bit (e.g. to 1.27mm) for this purpose.
• Probably it would look better to enable the grab area on the diode triangles, for consistency with single diodes?

I have shrunk the symbols down to 4x4, I added extra grab areas to triangles, picture below,

The 4x4 looks great IMO 👍 Regarding the grab area, maybe I was not clear enough, sorry. I meant to enable the "Grab Area" property of the already existing triangle polygons so the diodes are filled with yellow color the same way as single diodes. I quickly changed this by myself now (and also moved text labels in the EU symbol to the same position as in the US symbol):

Thanks for this contribution! 🎉
