Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The heat generated must be less than the thermal conductivity from Junction-to-Ambient: dPD/dTJ<1/θJA.
3. Measured at 1.0MHz and applied reverse voltage of 4.0V DC.
