Notes:
5. Device mounted on 1" x 1", Polymide PCB; 2 oz. Cu pad layout as shown on Diodes Inc. suggested pad layout document AP02001.pdf.
6. RoHS revision 13.2.2003. Glass and high temperature solder exemptions applied, see EU Directive Annex Notes 5 and 7.
7. Theoretical R_JS calculated from the top center of the die straight down to the PCB cathode tab solder junction.
8. Measured with I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A. See figure 5.
9. Short duration pulse test used to minimize self-heating effect.
10. Device mounted on FR-4 PCB, 2oz. Cu pad layout as shown on Diodes Inc. suggested pad layout document AP02001.pdf. (see page 2)
