Single Zener Diodes Procurement Notes

Verify the specific plating configuration required for your assembly process, as the base part number does not mandate a single finish. Confirm availability status carefully, as official notices indicate this SOD-323 package series has transitioned to End of Life status. Ensure compliance with RoHS directives if lead-free plating is necessary for your manufacturing standards.

Single Zener Diodes Selection Notes

Select this component when a precise 47 V reference is needed in a compact footprint. The 5% tolerance provides standard regulation accuracy suitable for general-purpose circuits. Consider the thermal resistance and power dissipation limits relative to your board's heat dissipation capabilities during continuous operation.

Single Zener Diodes Part Context

This device belongs to the CMDZ5221B through CMDZ5261B series of surface-mount silicon Zener diodes. The series covers a voltage range from 2.4 V to 47 V, all sharing the same 250 mW power rating and 5% tolerance specification within the SOD-323 package format.

Single Zener Diodes Replacement Considerations

Official documentation identifies CMDZ5261BF BK and CMDZ5261BF TR as suggested replacements. These substitutes utilize the SOD-323F case instead of the discontinued SOD-323 case.

Single Zener Diodes FAQ
