SOD-128 Component Package
Date Published: | |

Overview
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)1. 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.
Synonyms
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)
