Features
Notes: 1. Part mounted on 2"x2" GETEK board with 1"x1" copper pad, 25% anode, 75% cathode.
2. Part mounted on FR-4 board with recommended pad layout, which can be found on our website
at http://www.diodes.com/datasheets/ap02001.pdf.
3. Theoretical R
qJS
calculated from the top center of the die straight down to the PCB/cathode tab solder junction.
4. Short duration pulse test to minimize self-heating effect.
