Notes:
1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. 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. For Packaging Details, go to our website at http://www.diodes.com. 5. Add “-7” to the appropriate type number in Electrical Characteristics Table. Example: 6.2V Zener = DDZX6V2B-7. 6. 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.
