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 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 (R

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