The 1.5SMC30CA V7G: For a BOM line that already qualifies this part, that means no forced redesign on the horizon from the manufacturer's end.
The 38 A peak pulse current at that waveform tells you the diode can absorb a substantial transient without failing short. Clamps at 41.4 V maximum when hit with that 38 A pulse.
