SOD-123
The de-facto SOD-123 leads are gull-wing style (coming out the side of the package), whilst the SOD-123F variant has pads (on the underside of the package). It is the largest SOD package from the family including SOD-323, SOD-523, SOD-723 and SOD-923.

Dimensions And Recommended Footprint
Note that the pins in the above diagram are labelled with the diode anode being pin 2, and the cathode being pin 1. This is not what I would consider to be intuitive numbering!
SOD-123F
The SOD-123F component package has narrow, flat leads protruding from the base of the SMD package.
Synonyms:
- DO-219AA
- PDMU (Rohm)
- M1F (Fagor Electronica)
Pitch: 2.8mm
Recommended Footprint = 4.4x2.1mm = 9.2mm2
SOD-123EP
The SOD-123EP is a variant of the SOD-123 package with one of the pads being extended further underneath the package for improved power dissipation. This package is typically used for diodes, with the cathode connected to the larger pad1. Known as CASE 425AC by On Semi1.

- Length: 3.5mm
- Width: 1.7mm
- Height: 1.0mm
The above dimensions are nominal and include the leads (i.e. outer dimensions). This package the same nominal outer dimensions as the SOD-123F and SOD-123EP variants.
