DEFINITIONS
VF = Instantaneous forward voltage (pw = 300µs, D = 2%).
IR = Instantaneous reverse current.
tRR = Reverse recovery time (See Figure 2), summation of tA + tB.
tA = Time to reach peak reverse current (See Figure 2).
tB = Time from peak IRM to projected zero crossing of IRM based on a straight line from peak IRM through 25% of IRM (See Figure 2).
QRR = Reverse recovery charge.
CJ = Junction Capacitance.
RθJC = Thermal resistance junction to case.
EAVL = Controlled avalanche energy. (See Figures 10 and 11).
pw = pulse width.
D = duty cycle.
