(1)
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 conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2)
All voltage values are with respect to ANODE, unless otherwise noted.
(3)
Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
(4)
The package thermal impedance is calculated in accordance with JESD 51-7.
(5)
Maximum power dissipation is a function of TJ(max), θJC, and TC. The maximum allowable power dissipation at any allowable case
temperature is PD = (TJ(max) – TC)/θJC. Operating at the absolute maximum TJ of 150°C can affect reliability.
(6)
The package thermal impedance is calculated in accordance with MIL-STD-883.
