Part mounted on FR-4 PC board with recommended pad layout, which can be found on our website at http://www.diodes.com/package-outlines.html.
Short duration pulse test used to minimize self-heating effect.
The Zener impedances (Z
ZT
, Z
ZK
) are measured by superimposing a minute alternating current on the regulated current (I
Z
).
AEC-Q101 qualified.
