1. Avalanche failures assumption:
Purely a thermal phenomenon and failure occurs at a
temperature far in excess of T
jmax
. 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 12a, 12b.
4. P
D (ave)
= Average power dissipation per single
avalanche pulse.
5. BV = Rated breakdown voltage (1.3 factor accounts for
voltage increase during avalanche).
6. I
av
= Allowable avalanche current.

T
=
Allowable rise in junction temperature, not to exceed
T
