Notes:

1. Short duration pulse test used to minimize self-heating.

2. Part mounted on FR-4 PC board with minimum recommended pad layouts, which can be found on our website at

http://www/diodes.com/datasheets/ap02001.pdf.

3. No purposefully added lead. Halogen and Antimony Free.

4. 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 Sb2O3 Fire Retardants.
