Notes:
4. Short duration pulse test used to minimize self-heating effect.
5. Measured at 1.0MHz and applied reverse voltage of 0V DC.
6. Unit mounted on PC board with 5.0 mm² (0.013 mm thick) copper pads as heat sink.
7. Measured with I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A. See Figure 5.
8. Measured with I_F = 1.0A, di/dt = 100A/μS, Recovery to 1.0V.
