Notes:
1. Device mounted on FR-4 PCB with 10mm x 10mm pad, board size 35mm * 25mm.
2. No purposefully added lead. Halogen and Antimony Free.
3. Diodes Inc.'s "Green" policy can be found on our website at http://www.diodes.com/products/lead_free/index.php.
4. The Zener voltage is measured 40ms after power is supplied.
5. For inquiries on alternate nominal zener voltages, please contact your Diodes Inc. sales representative for availability and minimum order details.
6. f = 1kHz.
7. Short duration pulse test used to minimize self-heating effect.
