Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. The heat generated must be less than the thermal conductivity from Junction-to-Ambient: dPD/dTJ < 1/RqJA.
2. Proper strike and creepage distance must be provided.
3. Pulse Test: Pulse Width = 300 ms, Duty Cycle ≤ 2.0%.
