Zener Diodes
Features
• Silicon Planar Power Zener Diodes
• 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 desig-
nation DZ23 series.
17431
• The Zener voltages are graded according to the
international E 24 standard. Standard Zener volt-
age tolerance is ± 5 %. Replace suffix "C" with "B"
for ± 2 % tolerance. Other tolerances and other
Zener voltages are available upon request.
