Single Zener Diodes Procurement Notes

Verify the specific AEC-Q101 qualification status directly with the manufacturer or authorized distributors, as automotive compliance documentation is critical for this component series. Confirm that the SOD-123 footprint matches your PCB design constraints. Ensure that the 350 mW power dissipation rating aligns with your thermal management strategy under maximum load conditions before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 4.7 V reference is required in space-constrained automotive applications. The SOD-123 package offers a balance between power handling and board real estate efficiency. Consider the ±5% tolerance for general regulation tasks rather than high-precision instrumentation. Evaluate the low leakage current specification for sensitive circuit nodes where minimal standby current draw is essential.

Single Zener Diodes Part Context

This part belongs to Comchip Technology's ACZR series of automotive Zener diodes. The series is characterized by planar die construction and halogen-free materials, meeting strict environmental standards. These components are engineered specifically for the automotive sector, ensuring robust performance against vibration and thermal cycling common in vehicle electronics.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 4.7 V Zener voltage, 350 mW power rating, and SOD-123 package. Verify AEC-Q101 certification if automotive qualification is mandatory. Cross-reference parameters such as Zener impedance and leakage current to ensure circuit compatibility without redesign.
