Notes:
1. Non-repetitive current pulse , per Fig. 4 and derated above TJ (initial) =25OC per Fig. 3.
2. Mounted on copper pad area of 0.2x0.2” (5.0 x 5.0mm) to each terminal.
3. Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional
device only, duty cycle=4 per minute maximum.
4.VF < 3.5V for single die parts and VF< 5.0V for stacked-die parts.
5. The PPPM of stacked-die parts is 800W and please contact littelfuse for the detail
stacked-die parts.

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.
For parts with “*” are made by stack chip, which has higher surge capability (typical 1.8*IPP as specified).
