Typical Avalanche Current vs. Pulse Width Fig 15. Maximum Avalanche Energy vs. Temperature 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 16a, 16b. 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 13, 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 ( 1.3·BV·Iav) = DT/ ZthJC Iav = 2 DT/ [1.3·BV·Zth] EAS (AR) = PD (ave)·tav 25 50 75 100 125 150 175 Starting TJ , Junction Temperature (°C) 0 100 200 300 400 500 TOP Single Pulse BOTTOM 1.0% Duty Cycle ID = 62A 1E-006 1E-005 0.0001 0.001 0.01 0.1 1 t1 , Rectangular Pulse Duration (sec) 0.0001 0.001 0.01 0.1 1 0.20 0.10 D = 0.50 0.02 0.01 0.05 SINGLE PULSE ( THERMAL RESPONSE ) Notes: 1.
