(1) ^dIF^/dt
(1) dI_F/dt - rate of change of current
through zero crossing
(2) I_RRM - peak reverse recovery current
(3) t_rr - reverse recovery time measured
from zero crossing point of negative
going IF to point where a line passing
through 0.75 I_RRM and 0.50 I_RRM
extrapolated to zero current.
0.75 I _RRM
(4) Q_rr - area under curve defined by t_rr
and I_RRM
Qrr = ^{t rrx lRRM}
