Notes:
6. Part 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.
7. Short duration pulse test used to minimize self-heating effect.
8. The Zener impedances (ZZT, ZZK) are measured by superimposing a minute alternating current on the regulated current (IZ).
9. AEC-Q101 qualified
