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
