Notes: 1. Device mounted on FR-4 PC board with recommended pad layout, which can be found on our website at
http://www.diodes.com/datasheets/ap02001.pdf.
2. Valid provided the terminals are kept at ambient temperature.
3. No purposefully added lead. Halogen and Antimony Free.
4. f = 1KHz.
5. Short duration pulse test used to minimize self-heating effect.
6. Product manufactured with Data Code V9 (week 33, 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 Sb
