Absolute Maximum Ratings* TC=25°C unless otherwise noted
* These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.
NOTES:
1) These ratings are based on a maximum junction temperature of 150 degrees C.
2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations
Electrical Characteristics TC=25°C unless otherwise noted
* Pulse Test: Pulse Width ≤ 300µs, Duty Cycle ≤ 2.0%
