Single Zener Diodes Procurement Notes

Verify component authenticity through official NXP channels or authorized distributors. Confirm the specific suffix '115' matches procurement requirements as it denotes tape-and-reel packaging. Check current product status, as this item may be obsolete. Ensure RoHS compliance data aligns with project specifications before ordering.

Single Zener Diodes Selection Notes

Select this component when a 4.3 V Zener voltage with ±2% tolerance is required in a small SOT-346 package. Consider the 300 mW power rating and 90 Ohm impedance limits for thermal and dynamic performance. Verify that the surface-mount form factor fits the PCB layout constraints compared to through-hole alternatives.

Single Zener Diodes Part Context

This part belongs to the PZM4 series of single Zener diodes from NXP Semiconductors. The series offers various voltage options within the same SOT-346 (SC-59) plastic package, allowing for consistent footprint design across different voltage regulation needs. The 'NB3' designation typically indicates the specific voltage variant within this family.

Single Zener Diodes Replacement Considerations

Direct substitutes include other PZM4.3 variants such as PZM4.3NB1,115 or PZM4.3NB2,115, which share identical electrical characteristics but may differ in packaging configuration. Ensure any replacement maintains the SOT-346 footprint and 4.3 V/300 mW specifications.
