DZ23 Series
Vishay Semiconductors
Dual Common-Cathode Zener Diodes
Features
• This diode is also available in other case styles
and configurations including: the dual diode com-
mon cathode configuration with type designation
AZ23, the single diode SOT-23 case with the type
designation BZX84C, and the single diode
SOD-123 case with the type designation BZT52C.
• Dual Silicon Planar Zener Diodes, Common
Cathode
• The Zener voltages are graded according to the
international E 24 standard. Standard Zener volt-
age 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

and
∆r
