SOD-123 (Small-outline diode 123)
Reflow is most suitable. Easily solderable by hand for prototyping.
Typical PCB Land Area
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
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!
The SOD-123F component package has narrow, flat leads protruding from the base of the SMD package.
M1F (Fagor Electronica)
Recommended Footprint = 4.4x2.1mm = 9.2mm2
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. Known as
CASE 425AC by On Semi.
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.
