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. Part mounted on FR-4 PC boar
d with recommended pad layout, which can be found on our website at http://www.diodes.com/datasheets/ap02001.pdf.
5. Short duration pulse test used to minimize self-heating effect.
