Single Zener Diodes Procurement Notes

Verify the specific ordering suffix (e.g., RBG) against the manufacturer's official documentation to confirm packaging details such as tape and reel quantities. Confirm that the component meets RoHS compliance and JESD 201 class 1A whisker test standards required for your assembly process. Ensure the 0805 ceramic package dimensions align with your PCB footprint specifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a stable 9.1 V reference is needed in a compact surface-mount form factor. The 0805 ceramic package offers high thermal resistance and robust mechanical integrity compared to standard plastic packages. Consider the ±5% voltage tolerance and 500 mW power rating to ensure adequate headroom for your circuit design under varying load conditions.

Single Zener Diodes Part Context

This part belongs to the BZY55C series, which covers a wide Zener voltage range from 2.4 V to 36 V. All devices in this series share the same 0805 ceramic package and feature a single die configuration. The series is designed for general-purpose voltage regulation and reference applications requiring high reliability and parameter stability.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 0805 ceramic package, 9.1 V nominal voltage, and 500 mW power dissipation. Verify that alternative manufacturers offer components with equivalent leakage current and impedance characteristics to maintain circuit performance.
