[1] 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.
[2] Device mounted on an FR4 PCB, single-sided copper, tin-plated and standard footprint.
[3] Device mounted on an FR4 PCB, single-sided copper, tin-plated, mounting pad for cathode 1 cm2.
