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. Refer to SOT666 standard mounting conditions. Reflow soldering is the only recommended soldering method. Refer to SOD523 (SC-79) standard mounting conditions.
