Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only; and
functional operation of the device at these or any other condition beyond those indicated in the specifications is not implied. Exposure to absolutemaximum-rated conditions for extended periods may affect device reliability. The thermal resistance and power dissipation ratings are measured under
board mounted and still air conditions. Ambient temperature (TA) is 25°C, unless otherwise specified.

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 asT jmax is not
exceeded.
3. Equation below based on circuit and waveforms shown in Figures
22a, 22b.
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 T jmax
(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) = T/ ZthJC
Iav = 2T/ [1.3·BV·Zth]
