ted 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 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 14, 15). ta.
