Note: 1.
Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2.
Although not recommended, off-state voltages up to 800V may be applied without damage, but the triac
may switch to the on-state.
The rate of rise of current should not exceed 15A/μs.
