Notes:
9. The Zener voltage is measured 40ms after power is supplied.
10. For inquiries on tighter tolerances, or alternate nominal zener voltages, please contact your Diodes Inc. sales representative for availability and
minimum order details.
11. Short duration pulse test used to minimize self-heating effect.
