Usage ConsiderationsUsage ConsiderationsUsage ConsiderationsUsage Considerations Schottky barrier diodes (SBDs) have reverse leakage greater than other types of diodes. This makes SBDs more susceptible to thermal runaway under high-temperature and high-voltage conditions. Thus, both forward and reverse power losses of SBDs should be considered for thermal and safety design. 2014-04-14 2 Rev.5.0
