Notes:
1. EU Directive 2002/95/EC (RoHS). All applicable RoHS exemptions applied. Please visit our website at http://www.diodes.com/quality/lead_free.html.
2. Product manufactured with Data Code 0924 (week 24, 2009) and newer are built with Green Molding Compound.
3. Measured with I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A. See figure 5.
4. Measured at 1.0MHz and applied reverse voltage of 4.0V DC.
5. Short duration pulse test used to minimize self-heating effect.
