2. See http://www.diodes.com 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 OW (week 42, 2009) and newer are built with Green Molding Compound. Product manufactured prior to Date
Code OW are built with Non-Green Molding Compound and may contain Halogens or Sb2O3 Fire Retardants.
5. For Packaging Details, go to our website at http://www.diodes.com.
6. Add “-7” to the appropriate type number in Electrical Characteristics Table. Example: 6.2V Zener = DDZX6V2B-7.
7. Add “-13” to the appropriate type number in Electrical Characteristics Table. Example: 10V Zener = DDZX10C-13. Please note: Not all voltages are
available in 13” reel size. Please contact the Diodes Inc. Sales Department for assistance in ordering 13” reel size devices.
