Notes on Repetitive Avalanche Curves , Figures 14, 15:
(For further info, see AN-1005 at www.irf.com)
1. Avalanche failures assumption:
Purely a thermal phenomenon and failure occurs at a temperature far in
excess of Tjmax. This is validated for every part type.
2. Safe operation in Avalanche is allowed as long as neither Tjmax nor Iav (max)
is exceeded.
3. Equation below based on circuit and waveforms shown in Figures 22a, 22b.
4. PD (ave) = Average power dissipation per single avalanche pulse.
5. BV = Rated breakdown voltage (1.3 factor accounts for voltage increase
during avalanche).
6. Iav = Allowable avalanche current.
7.
T = Allowable rise in junction temperature, not to exceed Tjmax (assumed as
25°C in Figure 14, 15).
tav = Average time in avalanche.
D = Duty cycle in avalanche = tav f
ZthJC(D, tav) = Transient thermal resistance, see Figures 13)
PD (ave) = 1/2 ( 1.3BVIav) = DT/ ZthJC
Iav = 2
