Key Features

  • 2b. 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. ΔT = 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) 175 0 25 50 75 100 125 150 Starting TJ , Junction Tempe.
