1. dif/dt - Rate of change of current
through zero crossing
2. IRRM - Peak reverse recovery current
3. trr - Reverse recovery time measured
from zero crossing point of negative
going IF to point where a line passing
through 0.75 IRRM and 0.50 IRRM
extrapolated to zero current
4. Qrr - Area under curve defined by trr
and IRRM
trr X IRRM

5. di(rec)M/dt - Peak rate of change of
current during tb portion of trr
