Applications
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packing type and reel size. Confirm that the component version code aligns with required environmental standards. Ensure the lot number is recorded for tracking purposes as per manufacturer guidelines. Validate all electrical parameters against the latest datasheet revision before integration.
Selection Notes
Select this component when a dual Zener solution in a compact SOT-23 package is required. The common cathode arrangement allows for independent regulation or clamping functions. Verify that the 300 mW power rating and thermal resistance are sufficient for the target application's duty cycle and ambient conditions.
Part Context
This part belongs to the DZ23C2V4 series, which offers Zener voltages ranging from 2.4 V to 51 V. The series utilizes a standardized SOT-23 footprint to facilitate automated assembly processes. Other variants in the series share identical mechanical dimensions and maximum ratings while differing in specific voltage and impedance characteristics.
Replacement Considerations
Cross-reference with other manufacturers offering dual Zener diodes in SOT-23 packages. Ensure equivalent Zener voltage, power dissipation, and leakage current specifications are met. Verify pinout compatibility and thermal performance characteristics before substitution.
FAQ
What is the maximum reverse leakage current for the DZ23C28?
The maximum reverse leakage current is 0.1 μA when measured at a reverse voltage of 22.0 V.
Is the DZ23C28 available in a common anode configuration?
No, the DZ23C28 is specifically a common cathode device. The datasheet indicates that common anode styles are available in the AZ Series.
