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
qJA
), power dissipation rating (P
d
) and power derating curve (figure 1).
