Small Signal Zener Diodes, Dual
FEATURES
2
1
• Dual silicon planar Zener diodes, common
anode
• The Zener voltages are graded according to the
international E24 standard. Standard Zener
voltage tolerance is ± 5 %, indicated by the “C”
in the ordering code. Replace “C” with “B” for
2 % tolerance.
• The parameters are valid for both diodes in one
case.
V
Z
and
R
zj
of the two diodes in one
case is
5 %
• AEC-Q101 qualified available
• ESD capability according to AEC-Q101:
Human body model > 8 kV
Machine model > 800 V
