Limiting values[1] Device mounted on an FR4 Printed-Circuit Board (PCB), single-sided copper, tin-plated and standard
footprint.
[2] Device mounted on an FR4 PCB, single-sided copper, tin-plated, mounting pad for cathode 1 cm2.
Thermal characteristics[1] For Schottky barrier diodes thermal run-away has to be considered, as in some applications the reverse
power losses PR are a significant part of the total power losses. Nomograms for determining the reverse
power losses PR and IF(AV) rating will be available on request.
