- Notes: 1. EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3).compliant. All applicable RoHS exemptions applied 

   2. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free 

   3. Valid provided that leads are maintained at ambient temperature at a distance of 9.5mm from the case. 

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

5. Measured with IF = 0.5A, IR = 1.0A, Irr = 0.25A. See figure 5. 

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