SOD-128
is a package used by a few manufacturers for diodes. I could not find any JEITA (EIAJ) code (e.g. SC-xxx
) for this package. ST Microelectronics calls this package the SOD-128 FLAT
(presumably because it has flat leads, as opposed to many SOD packages which by default have gull-wing leads, and only offer flat variants once you add a F
suffix)4. There does not appear to be any difference between the ST Microelectronics SOD-128 FLAT
package and the SOD-128
as labelled by Rohm and Nexperia.
Thermal Resistance
\(R_{JA} = 200^{\circ}{\rm C}/W\)
(standard land pattern, see below)\(R_{JA} = 120^{\circ}{\rm C}/W\)
(mounting pad for cathode 1cm²)\(R_{JA} = 60^{\circ}{\rm C}/W\)
(mounted on ceramic PCB with standard footprint)
