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 asTjmax is not exceeded. 3. Equation below based on circuit and waveforms shown in Figures 17a, 17b. 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 25C in Figure 14, 15). t av = Average time in avalanche. D = Duty cycle in avalanche = tav *f ZthJC(D, tav) = Transient thermal resistance, see figure 11) PD (ave) = 1/2 ( 1.3*BV*Iav) = DT/ ZthJC Iav = 2DT/ [1.3*BV*Zth] EAS (AR) = PD (ave)*tav
