Key Features

  • ) = 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). 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 = 2DT/ [1.3.
  • BV.
