I want to use this component in my design: https://datasheet.lcsc.com/lcsc/2201121330_JSMSEMI-1N5819WS-S4_C2927280.pdf

It says that the footprint is SOD-323. I couldn't find this footprint in KiCAD's library.

Is this footprint available, or do I have to create it myself?

Yes, it's available under the name "D_SOD-323".

enter image description here

Note: The pad size of the recommanded footprint from the datasheet is even bigger than the hand soldering variant from KiCAD. If you want to follow the datasheet, you'll have to create your own footprint. Personally, I think the pads in the datasheet are comically large and would use the KiCAD footprints.

  • \$\begingroup\$ Thanks! Do you propose i use the Standard, or the HandSoldering version? \$\endgroup\$ Jun 15, 2023 at 22:02
  • \$\begingroup\$ @user1584421 For soldering with a soldering iron, I would use the hand soldering version. The normal version is very small and can be frustrating to work with, especially if your hands are not steady. \$\endgroup\$

  • \$\begingroup\$ I intend to use an assembly service. Therefore I am not interested in soldering it by hand. I just asked because the HandSoldering version seems longer. I am afraid that the footprint will be smaller that the actual device (according to its datasheet at least). I have never heard of a datasheet with having wrong dimensions. \$\endgroup\$ Jun 16, 2023 at 12:39
  • \$\begingroup\$ @user1584421 Change the footprint to the dimensions from the datasheet, look at it in the 3D viewer and you will see what I mean by "comically" large. I've used the standard footprint before for home reflow soldered PCBs and it worked fine (sucks for re-working though). \$\endgroup\$

  • \$\begingroup\$ OK, Thanks, I will stick to KiCad's footprint (NOT the HandSoldering one). \$\endgroup\$ Jun 16, 2023 at 13:49
