Notes:
3. Short duration pulse test used to minimize self-heating effect.
4. Valid provided that leads are maintained at ambient temperature at a distance of 9.5mm from the case.
5. Measured with IF = 0.5A, IR = 1.0A, Irr = 0.25A. See figure 5.
6. Measured at 1.0MHz and applied reverse voltage of 4.0V DC.
