Features
• Dual Silicon Planar Zener Diodes, Common
Cathode
• 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.
• The parameters are valid for both diodes in one
case.

• This diode is also available in other case styles and
configurations including: the dual diode common
cathode configuration with type designation AZ23,
the single diode SOT-23 case with the type desig-
nation BZX84C, and the single diode SOD-123
case with the type designation BZT52C.
