DEFINITIONS
V
F
= Instantaneous forward voltage (pw = 300
µ
s, D = 2%).
I
R
= Instantaneous reverse current.
t
rr
= Reverse recovery time (See Figure 9), summation of t
a
+ t
b
.
t
a
= Time to reach peak reverse current (See Figure 9).
t
b
= Time from peak I
RM
to projected zero crossing of I
RM
based on a straight line from peak I
RM
through 25% of I
RM
(See Figure 9).
Q
RR
= Reverse Recovery Charge.
C
J
= Junction Capacitance.
R
θ
JC
= Thermal resistance junction to case.
pw = Pulse Width.
D = Duty Cycle.
