Small Signal Zener Diodes, Dual
FEATURES
• Dual silicon planar Zener diodes, common
cathode
• The Zener voltages are graded according to the
international E24 standard. Standard Zener
voltage tolerance is ± 5 %. Replace “C” with “B”
for 2 % tolerance
• The parameters are valid for both diodes in one case. VZ
and Rzj of the two diodes in one case is 5 %
• AEC-Q101 qualified
• Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
