Procurement Notes
Verify the specific ordering suffix when sourcing components. The datasheet indicates that adding “-7-F” to the type number designates commercial qualification packaged in tape and reel format. Confirming the exact suffix ensures alignment with the required qualification level and packaging specifications for production integration.
Selection Notes
Select this component for applications requiring a dual Zener array in a compact SOT-23 footprint. Ensure the operating voltage falls within the 4.4V to 5.0V range and verify that the 300mW power dissipation rating accommodates the thermal requirements of the target circuit environment.
Part Context
This part belongs to the DZ23C series, which covers a wide range of Zener voltages from 2.7V to 51V. All devices in this family share identical mechanical dimensions and electrical characteristics regarding power dissipation and thermal resistance, differing primarily in their breakdown voltage specifications.
Replacement Considerations
For automotive applications requiring specific change control, refer to the related automotive grade (Q-suffix) parts listed on the manufacturer's website. Other dual Zener arrays in SOT-23 packages may be considered if electrical parameters match the design requirements.
