Notes:
1. Part mounted on FR-4 board with recommended pad layout, which can be found on our website at http://www.diodes.com/datasheets/ap02001.pdf.
2. Short duration pulse test used to minimize self-heating effect.
3. No purposefully added lead. Halogen and Antimony Free.
4. Product manufactured with Date Code V9(week 34, 2008) and newer are built with Green Molding Compound. Product manufactured prior to Date Code
V9 are built with Non-Green Molding Compound and may contain Halogens or Sb2O3 Fire Retardants.
