Notes:
1. Measured with IF = 0.5A, IR = 1.0A, Irr = 0.25A. See figure 5.
2. Measured at 1.0MHz and applied reverse voltage of 4.0V DC.
3. Unit mounted on PC board with 5.0 mm2 (0.013 mm thick) copper pad as heat sink.
4. RoHS revision 13.2.2003. Glass and high temperature solder exemptions applied, see EU Directive Annex Notes 5 and 7.
5. Short duration pulse test used to minimize self-heating effect.
