Correct SOT-143
Corrected footprint dimensions for standard SMD instead of wave soldering.
Related to #2381 .
Datasheets for this package:
- onsemi: https://www.onsemi.com/pub/Collateral/318A.PDF
- diodes: https://www.diodes.com/assets/Package-Files/SOT143.pdf
- nxp/nexperia: https://assets.nexperia.com/documents/package-information/SOT143B.pdf
The 3D model seems to not be correct according to the datasheets.
Before:
After:
The same applies to the _Reversed
and _Reversed_Handsolder
footprints
I assumed you used the diodes datasheet? I checked against that one.
- [x] Pad numbering and Position is good.
- [x] F.Fab is good
- [x] Courtyard is good
- [ ] Please add a datasheet link into the description
- [ ] Silkscreen should move outwards a little. It should not overlap the F.Fab line. Like so
- [ ] The reverse part should be rotated so that pin1 is in the upper-left quadrant
- [ ] I am unsure how to check the handsoldering parts. Is there any rule you applied to elongate the pads?

I don't remember which datasheet i ended up using as a guideline, but i believe i checked them all against each other and they were the same or very close to the same dimensions (if I'm remembering correctly) so it shouldn't matter too much.

done. I added NXP's references because they had a both the normal SOT-143 and the reverse pinning version and so it is more consistent.

I looked for guidelines, but since i didn't find any i just did what felt right to me, the pins are slightly shorter than the original hand-solder versions
