The 45 V reverse voltage (Vr) is the maximum DC blocking voltage the diode can withstand. ## 10 A average current — sizing the load budget The 10 A average rectified current (Io) is the continuous DC load the diode can handle with proper heatsinking. ## 630 mV forward drop at 10 A — the efficiency number At 10 A forward current the typical forward voltage is 630 mV. ## Lifecycle and supply reality That makes it safe to qualify for a new production BOM.
