TemperatureNotes on Repetitive Avalanche Curves , Figures 15, 16:(For further info, see AN-1005 at www.irf.com)1. Avalanche failures assumption:Purely a thermal phenomenon and failure occurs at atemperature far in excess of Tjmax. This is validated forevery part type.2. Safe operation in Avalanche is allowed as long asTjmax isnot exceeded.3. Equation below based on circuit and waveforms shown inFigures 12a, 12b.4. PD (ave) = Average power dissipation per singleavalanche pulse.5. BV = Rated breakdown voltage (1.3 factor accounts forvoltage increase during avalanche).6. Iav = Allowable avalanche current.7.∆T = Allowable rise in junction temperature, not to exceedTjmax (assumed as 25°C in Figure 15, 16).tav = Average time in avalanche.D = Duty cycle in avalanche = tav ·fZthJC(D, tav) = Transient thermal resistance, see figure 11)PD (ave) = 1/2 ( 1.3·BV·Iav) = ∆∆∆∆∆T/ ZthJCIav = 2∆∆∆∆∆T/ [1.3·BV·Zth]EAS (AR) = PD (ave)·tav255075100125150175Starting T J , Junction Temperature (°C)0100200300400500TOPSingle PulseBOTTOM 10% Duty CycleID = 95A1.0E-081.0E-071.0E-061.0E-051.0E-041.0E-031.0E-021.0E-01tav (sec)11010010000.05Duty Cycle = Single Pulse0.10Allowed avalanche Current vsavalanchepulsewidth,tavassuming∆ Tj = 25°C due toavalanche losses0.01
