fo
r more information about Diodes Incorporated’s definitions of Hal
ogen- 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.
