Hi,
Does PCB Libraries automate the creation of JEDEC TO-277 parts? It's not quite a 3-Pin DFN, since the pads stick out beyond the body. I think I have to make it by hand, but I figured I should check to see if I'm missing something. --John

I tried using the DFN 3-Pin option, and it mostly worked. The only issue is the 3D model of the pads where they stick out is wrong.

The JEDEC TO-277 is normally FP Designer footprint but you may trick the 3-Pin DFN by using the Footprint Tab to insert the mfr. recommended pattern data.
Either way, an accurate 3D STEP model needs to be manually created. |

Here is the JEDEC TO-277A STEP file that should also match Vishay -
Download STEP file here: JEDEC_TO-277A.zip This STEP file is in the Top Plane Rotation Y. You can use the Library Expert - Tool Box - to rotate the model to the Z axis (Right Plane). |
