2. SOD-123
The SOD-123 component package is a medium sized, 2-lead SMD package, commonly used for packaging diodes. The 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
.

2.1. 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!
3. 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




4. 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 pad[1]. Known as CASE 425AC
by On Semi[1].
5. SOD-123W
Synonyms:
Dimensions[2]:
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.
