      *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°C.
       2) These are steady state limits.  The factory should be consulted on applications involving pulsed or low duty cycle operations.
