FEATURES
Silicon Planar Power Zener Diodes
The Zener voltages are graded according to the international
E 24 standard. Standard Zener voltage tolerance
is 5%. Replace suffix "C" with "B" for 2% toler-
ance. Other tolerances and other Zener voltages
are available upon request.
These diodes are also available in other case styles and other
configurations including: the SOT-23 case with type designation
BZX84 series, the dual zener diode common anode configuration
in the SOT-23 case with type designation AZ23 series and the
dual zener diode common cathode configuration in the SOT-23
case with type designation DZ23 series.
