Single Zener Diodes Procurement Notes

Verify that the ordering code matches the specific suffix requirements for tape and reel quantities. Confirm RoHS compliance status and AEC-Q101 qualification if automotive grade is required. Ensure the component marking code aligns with the specified 30 V Zener voltage rating before integration into production lines.

Single Zener Diodes Selection Notes

Select this component when a 30 V reference with tight ±5% tolerance is necessary. The DO-214AC package suits automated surface mount assembly processes. Consider the 40 Ω dynamic impedance for load regulation requirements. Verify thermal management capabilities for continuous 1 W power dissipation at elevated ambient temperatures.

Single Zener Diodes Part Context

This part belongs to the SML4728 to SML4764A series of surface mount Zener diodes. The series covers a wide voltage range from 3.3 V to 100 V. All devices share the same DO-214AC footprint and mechanical specifications, allowing for design flexibility across different voltage requirements within the same product family.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' SMA packaged Zener diodes rated at 30 V with similar power and tolerance specifications. Cross-reference electrical characteristics such as dynamic impedance and leakage current to ensure circuit compatibility without redesign.
