1. RT to 160°: 100-150 second
2. 150° to 200°: around 60 seconds
3. 200° to 270°: around 60 seconds
4. Peak temperature and time: 270±5°: 3 ±0.5sec
5. 270° to RT: at least 120 seconds
At idle power, current levels shown to the left of the diskontinuity illustrate typically the high end leakage current. However, if lower leakage current
levels are desired, they may be guaranteed. In the clamping voltage region to the right of the diskontinuity, maximum clamping voltage is plotted.
