Notes:
Calculated continuous current based on maximum allowable junction temperature. Bond wire current limit is 240A by
source bonding technology. Note that current limitations arising from heating of the device leads may occur with
some lead mounting arrangements. (Refer to AN-1140)
Repetitive rating; pulse width limited by max. junction temperature.
 Limited by TJmax, starting TJ = 25°C, L = 0.077mH, RG = 50, IAS = 100A, VGS =10V.
ISD  100A, di/dt  969A/µs, VDD  V(BR)DSS, TJ 150°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.
 R is measured at TJ approximately 90°C.
 Limited by TJmax, starting TJ = 25°C, L = 1mH, RG = 50, IAS = 42A, VGS =10V.
 When mounted on 1" square PCB (FR-4 or G-10 Material). Please refer to AN-994 for more details:

(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
23a, 23b.
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) = T/ ZthJC
Iav = 2T/ [1.3·BV·Zth]
EAS (AR) = PD (ave)·tav Submit Datasheet Feedback
