Procurement Notes
Verify the specific ordering suffix to confirm packaging configuration and compliance status. Ensure the supplier provides traceability documentation consistent with onsemi quality standards. Confirm that the received components match the specified SOD-323 package dimensions and marking codes before integration into production lines.
Selection Notes
Select this component when a precise 3.15V reference is required in a compact surface-mount form factor. Consider the maximum power dissipation capabilities relative to the expected thermal environment. Evaluate the tolerance requirements against the standard specifications provided in the official datasheet to ensure adequate performance margins for the target application.
Part Context
This part belongs to onsemi's portfolio of small-signal Zener diodes optimized for modern electronics. The STZD series focuses on providing reliable voltage regulation in minimal footprints. These components are widely utilized in consumer electronics and industrial control systems where space efficiency and thermal robustness are critical design constraints.
Replacement Considerations
Consult official cross-reference lists for compatible alternatives. Verify that any substitute matches the 3.15V nominal voltage, SOD-323 package, and 175°C temperature rating. Ensure electrical parameters such as impedance and leakage current remain within acceptable limits for the specific circuit design.
