(For further info, see AN-1005 at www.irf.com)
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 asTjmax 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. โT = Allowable rise in junction temperature, not to exceed
Tjmax (assumed as 25ยฐC in Figure 15, 16).
tav = Average time in avalanche.
D = Duty cycle in avalanche = tav ยทf
ZthJC(D, tav) = Transient thermal resistance, see figure 11)
PD (ave) = 1/2 ( 1.3ยทBVยทIav) = DT/ ZthJC
Iav = 2DT/ [1.3ยทBVยทZth]
