DEFINITIONS
V_F = Instantaneous forward voltage (pw = 300µs, D = 2%).
I_R = Instantaneous reverse current.
t_RR = Reverse recovery time (See Figure 2), summation of t_A + t_B.
t_A = Time to reach peak reverse current at (See Figure 2).
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 2).
R_θJC = Thermal resistance junction to case.
E_AVL = Controlled avalanche energy (See Figures 7 and 8).
pw = pulse width.
D = duty cycle.
