Absolute Maximum Ratings
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only; and functional operation of the device at these or any other condition beyond those indicated in the specifications is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions. Ambient temperature (T A) is 25C, unless otherwise specified.

Notes: Repetitive rating; pulse width limited by max. junction temperature. (See fig. 11). Limited by TJmax, starting TJ = 25C, L =0.18mH, RG = 25, IAS = 31A, VGS =10V. Part not recommended for use above this value. ISD 31A, di/dt 840A/s, VDD V(BR)DSS, TJ 175C. Pulse width 1.0ms; duty cycle 2%.
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, starting 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. R is rated at TJ of approximately 90C. TJ = 25C, L =0.18mH, RG = 25, IAS = 31A, VGS =10V.

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 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. T = Allowable rise in junction temperature, not to exceed Tjmax (assumed as 25C 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
