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 test pulse 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 (RqJA), power dissipation rating (Pd) and power derating curve (figure 1).
