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. When operated under collector-emitter saturation conditions within the safe operating area defined by the thermal resistance rating (R
θJA
), power
dissipation rating (P
d
) and power derating curve (Figure 1).
3. No purposefully added lead.
4. Diodes Inc.'s "Green" policy can be found on our website at http://www.diodes.com/products/lead_free/index.php.
5. Product manufactured with Date Code 0627 (week 27, 2006) and newer are built with Green Molding Compound. Product manufactured prior to Date
Code 0627 are built with Non-Green Molding Compound and may contain Halogens or Sb2O3 Fire Retardants.
