Comparison between Melf and SMA package

Build in massive copper plugs

Build in copper leadframe technology

Superior thermal resistance due to massive 
plugs removing heat easily

Leadframe technology possess higher thermal
resistance

Superior surge current rating due to high heated capacity of plugs, absorbing easily short lasting high energy surges

Leadframe technology has got less heat capacity

Tends to “roll away” during assembly, therefore
better fitted for wave soldering
(where devices are glued to the PCB)

Applicable to all kinds of welding such as reflow or wave soldering

More sensitive against mechanical forces
applied to the plugs

Leadframe technology provides better stress
relief, therefore less sensitivity against mechanical stress to the leads
