Cross-reference datasheet revisions to ensure compatibility with current design requirements.

Single Zener Diodes Selection Notes

Select this component when designing for automotive environments requiring strict voltage tolerance and extended temperature ranges. The SOD-123-2 package offers a balance between power handling and board space efficiency. Ensure the circuit design accounts for the 500 mW power dissipation limit under worst-case thermal conditions.

Single Zener Diodes Part Context

This component belongs to Comchip Technology's ABZT series of automotive Zener diodes. The series is engineered specifically for the automotive industry, offering enhanced durability and stability compared to standard commercial-grade devices. It complements other components in voltage regulation and protection strategies within vehicle electronics.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 30 V Zener voltage, 2% tolerance, 500 mW power rating, and SOD-123-2 package. Verify that any alternative component also holds AEC-Q101 certification if automotive qualification is required. Check thermal resistance and leakage current specifications for electrical equivalence.
