Intrinsic turn-on time is negligible (turn-on is dominated by LS+LD)
Coss eff. is a fixed capacitance that gives the same charging time
as Coss while VDS is rising from 0 to 80% VDSS .
Limited by TJmax , see Fig.12a, 12b, 15, 16 for typical repetitive
avalanche performance.
This value determined from sample failure population. 100%
tested to this value in production.
This is applied to D2Pak, when mounted on 1" square PCB
( FR-4 or G-10 Material ). For recommended footprint and
soldering techniques refer to application note #AN-994.
Rθ is rated at TJ of approximately 90°C.

Notes on Repetitive Avalanche Curves , Figures 15, 16:
(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 T jmax. 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. ∆T = Allowable rise in junction temperature, not to exceed
Tjmax (assumed as 25°C in Figure 15, 16).
tav = Average time in avalanche.
D = Duty cycle in avalanche = tav ·f
ZthJC(D, tav ) = Transient thermal resistance, see figure 11)
PD (ave) = 1/2 ( 1.3·BV·Iav) = DT/ ZthJC
Iav = 2DT/ [1.3·BV·Zth]
EAS (AR) = PD (ave)·tav
