2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green"
and Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and
<1000ppm antimony compounds.
4. Product manufactured with Date Code 9W (week 39, 2009) and newer are built with Green Molding Compound. Product manufactured prior to Date
Code 9W are built with Non-Green Molding Compound and may contain Halogens or Sb2O3 Fire Retardants.
