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. ∆VZ and ∆rzj of the two diodes in one case is ≤ 5% • 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 designation BZX84C, and the single diode SOD-123 case with the type designation BZT52C.
