Note: 1. Although not recommended, off-state voltages up to 800V may be applied without damage, but the thyristor
may switch to the on-state. The rate of rise of current should not exceed 15A/μs.
2. 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.
