Notes:
1. Non-repetitive current pulse , per Fig. 4 and derated above TJ (initial) =25OC per Fig. 3.
2. Measured on 8.3ms single half sine wave or equivalent square wave, duty cycle=4 per minute maximum.
3. VF < 3.5V for single die parts and VF< 5.0V for stacked-die parts.
4. For stacked die component details, please refer to part numbers labeled by * in Electrical Characteristics.

For bidirectional type having VR of 10 volts and less, the IR limit is double.
For parts without A, the VBR is ± 10% and VC is 5% higher than with A parts, the parts without A are currently available, but not recommended for new designs. The parts with A are preferred.
For stack-die parts, use * to label the part number.
