Notes: 1. This is the maximum rating of single Diode (D1
or D
2
or D
3). In the case of using two or three diodes, the maximum ratings per diode are 75% of the
ratings for single diode operation.
2. Short duration pulse test used to minimize self-heating effect.
3. No purposefully added lead.
4. 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.
5. Diodes Inc.'s "Green" policy can be found on our website at http://www.diodes.com/products/lead_free/index.php.
6. Product manufactured with Date Code UO (week 40, 2007) and newer are built with Green Molding Compound. Product manufactured prior to Date
Code UO are built with Non-Green Molding Compound and may contain Halogens or Sb2O3 Fire Retardants.
