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 absolute-maximum-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.

Limited by TJmax, starting TJ = 25°C, L = 0.09mH, RG = 25, IAS = 52A, VGS =10V. Part not recommended for use above this value.
Pulse width 1.0ms; duty cycle 2%.

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 as Tjmax is not exceeded.
3. Equation below based on circuit and waveforms shown in Figures 12a, 12b.
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).
t
av = Average time in avalanche.
D = Duty cycle in avalanche = tav ·f
Z
thJC(D, tav) = Transient thermal resistance, see Figures 13)
