Single Zener Diodes Procurement Notes

Verify that the ordering code matches the specific suffix requirements for tape and reel packaging. Confirm RoHS compliance status and ensure the selected variant aligns with the required tolerance class. Cross-reference the manufacturer part number against official distribution channels to validate authenticity before procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 47 V reference is needed in a compact surface-mount footprint. The ±2% tolerance makes it suitable for applications demanding tighter voltage accuracy than standard commercial grades. Ensure the circuit design accommodates the specified thermal resistance and power dissipation limits under expected operating conditions.

Single Zener Diodes Part Context

This device belongs to the MMSZ5225 to MMSZ5267 series of small signal Zener diodes. The 'C' suffix indicates the specific ±2% tolerance grade, while the '-E3-18' suffix denotes RoHS compliance and 10,000-unit tape and reel packaging. It shares the SOD-123 package form factor common across the broader family.

Single Zener Diodes Replacement Considerations

MMSZ5261B-E3-18 offers equivalent electrical performance with a wider ±5% tolerance specification.
