Notes:
1. Device mounted on FR-4 PCB, 1 inch x 0.85 inch x 0.062 inch; pad layout as shown on Diodes Inc. suggested pad layout document AP02001, 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. When operated under collector-emitter saturation conditions within the safe operating area defined by the thermal resistance rating (RθJA), power
dissipation rating (Pd) and power derating curve (figure 1).
4. No purposefully added lead. Halogen and Antimony Free.
5. 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.
