**Screenshot:**

KLC violations:

• Violating F5.2: RefDes text size (0.25mm) is outside allowed range [0.5mm - 1.0mm]
  The text size is in line with other parts of the same size (e.g. R_0201_0603Metric)
• Violating F6.3: Pads '1' and '2' potentially missing layers
  As specified in the datasheet the paste is defined by circles (nod rectangular like the shape)

This footprint may be used with standard Device:D_TVS or Device:D_Schottky.
