Features

• Dual Silicon Planar Zener Diodes, Common Anode
• 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.
∆V
Z
and
∆r
zj
of the two diodes in one case is
≤
5%
• These diodes are also available in other case styles and
configurations including: the dual diode common
cathode configuration with type
designation DZ23, the single diode SOT-23 case with
the type designation BZX84C, and the single diode
SOD-123 case with the type designation BZT52C.
