VR = 10V
VR = 1V f = 1.0 MHz
Notes: 1. Short duration test pulse to minimize self-heating effect.
2. Device mounted on FR-4 PC board with recommended pad layout, which can be found on our website at http://www.diodes.com/datasheets/ap02001.pdf.
3. No purposefully added lead.
4. Diodes Inc.'s "Green" policy can be found on our website at http://www.diodes.com/products/lead_free/index.php.
5. Product manufactured with Date Code 0609 (week 9, 2006) and newer are built with Green Molding Compound. Product
manufactured prior to Date Code 0609 are built with Non-Green Molding Compound and may contain Halogens or Sb2O3 Fire Retardants.
6. Package is non-polarized. Parts may be on reel in orientation illustrated, 180° rotated, or mixed (both ways).
