A
=25°C unless otherwise noted
* These ratings are limiting values above which the serviceability of any semiconductor device may be impaird.
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
