Notes: 1. Valid provided that leads are kept at ambient temperature at a distance of 9.5mm from the case.
2. Measured with I
3. Measured at 1.0MHz and applied reverse voltage of 4.0V DC.
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.
