Notes: 1. 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.
2. Short duration test pulse used to minimize self-heating effect.
3. The zener impedances (ZZT, ZZK) are measured by superimposing a minute alternating current on the regulated current (IZ).
4. No purposefully added lead.
