Notes:
6. Part mounted on 2"x2" GETEK board with 1"x1" copper pad, 25% anode, 75% cathode. T_A = +25°C.
7. Part mounted on FR-4 board with recommended pad layout, which can be found on our website at http://www.diodes.com.
8. Theoretical R_ΘJS calculated from the top center of the die straight down to the PCB/cathode tab solder junction.
9. Short duration pulse test used to minimize self-heating effect.
