2. S

ee 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. Automotive products are AEC-Q101 qualified and are PPAP capable. Automotive, AEC-Q101 and standard products are electrically and thermally

the same, except where specified. For more information, please refer to
