Notes:

5. Short duration pulse test used to minimize self-heating effect.

6. Measured with IF = 0.5A, IR = 1.0A, IRR = 0.25A. See figure 7.

7. Measured at 1.0MHz and applied reverse voltage of 4.0V DC.

8. Device mounted on FR-4 substrate, 1" * 1", 2oz, single-sided, PC boards with 0.1"*0.15" copper pads.

9. Device mounted on FR-4 substrate, 0.4" * 0.5", 2oz, single-sided, PC boards with 0.2"*0.25" copper pads.
