Zero
4 trr - Reverse Recovery Time, measured from zero crossing where diode
current goes from positive to negative, to the point at which the straight

line through I_RRM and 0.25 I_RRM passes through zero.
5 Qrr - Area Under the Curve Defined by I_RRM and trr.
6 di_M/dt - Maximum Rate of Current Increase During the Trailing Portion of trr.
