Pb Free RoHS compatible devices will have a “#” marked on the top or bottom of the package to denote compatibility. Several of the packages (SOT23, SC70 and TSOT) are too small to accommodate an additional character, and as a result, there will be no “#” marking on the device. For these small packages, a unique brand code is used for most products to denote the Pb Free RoHS compatible device. Over the next several months, ADI will review capability of marking per JESD97 industry standard. If feasible, we will adopt this standard marking in place of the “#” as our Pb Free RoHS compatible marking.
