Notes:
6. Part mounted on 50.8mm X 50.8mm GETEK board with 25.4mm X 25.4mm copper pad, 25% anode, 75% cathode. TA = +25°C.
7. Part mounted on FR-4 board with 1.8mm X 2.5mm cathode and 1.8mm X 1.2mm anode, 1 oz. copper pads. TA = +25°C.
8. Theoretical RθJS 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.
