Note:
1. For bidirectional type having VR of 10 volts and less, the IR limit is double.
2. 100% High Temperature Storage Life test and Reflow Simulation.
3. 100% HTRB(High Temperature Reverse Bias). For Unidirectional, 150OC/100%VR/96hours,
for Bidirectional, 150OC/100%VR/192hrs(96hours for each direction for Bidirectional).
4. IR measured at room temperature +25OC
5. Each lot of parts will pass group B test requirement.
