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 (TA) is 25°C, unless
otherwise specified.

Notes:
Repetitive rating; pulse width limited by max. junction temperature. (See fig. 11)
Limited by TJmax , starting TJ = 25°C, L = 0.12mH, RG = 25, IAS = 42A, VGS =10V. Part not recommended for use above this value.
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 TJ = 25°C, L = 0.12mH, RG = 25, IAS = 42A, VGS =10V.
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 measured at TJ approximately 90°C.

Purely a thermal phenomenon and failure occurs at a temperature far in
excess of Tjmax. This is validated for every part type.
