For PMDTM diodes, Rohm will have a common part marking standard for all types of diodes. Similar to the Wide Frame PMDU, the PMDTM will also run a scan laser directly onto the package. Parts will have 30 dots instead of just numbers for conventional PMDS diodes. This will provide additional Date and Lot code information for each diode. The scan method also provides more consistency and precision when marking the parts.
