Notes:
1. Device mounted on ceramic PCB = 7.6mm x 9.4mm x 0.87mm with pad areas 25mm² at T_A = 25°C or mounted on FR-5 = 3.5x1.5 inches with
recommended pad layout, which can be found on our website at http://www.diodes.com/datasheets/ap02001.pdf, at T_L = 75°C.
2. No purposefully added lead. Halogen and Antimony Free.
3. 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.
