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

t rr and IRRM
