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