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 “C” with “B” for ±2%
tolerance. Other voltage tolerances and other
Zener voltages are available upon request.
• These diodes are also available in other case
styles and other configurations including: the
SOD-123 case with type designation BZT52 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.
