ISD ≤ 46A, di/dt ≤ 1920A/µs, VDD ≤ V(BR)DSS, TJ ≤ 175°C.
Pulse width ≤ 400µs; duty cycle ≤ 2%.
Coss eff. (TR) is a fixed capacitance that gives the same charging time
as Coss while VDS is rising from 0 to 80% VDSS.
Coss eff. (ER) is a fixed capacitance that gives the same energy as
Coss while VDS is rising from 0 to 80% VDSS.
When mounted on 1" square PCB (FR-4 or G-10 Material). For recom-
mended footprint and soldering techniques refer to application note #AN-994.
Rθ is measured at TJ approximately 90°C.
Notes:
Calculated continuous current based on maximum allowable junction
temperature. Bond wire current limit is 56A. Note that current
limitations arising from heating of the device leads may occur with
some lead mounting arrangements.
Repetitive rating; pulse width limited by max. junction

Notes on Repetitive Avalanche Curves , Figures 14, 15:
(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 16a, 16b.
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).
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) = DT/ ZthJC
Iav = 2DT/ [1.3·BV·Zth]
