Single Zener Diodes Procurement Notes

Verify that the ordering suffix "-TP" corresponds to the Tape & Reel packaging configuration containing 3,000 units per reel as specified in the manufacturer's ordering information. Confirm compliance with environmental standards such as RoHS and Halogen-Free status through official documentation or distributor certifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a stable 8.2 V reference is required in space-constrained designs utilizing the SOD-123 footprint. Ensure the application current remains within the specified limits to maintain the ±5% voltage tolerance. Consider the 500 mW power dissipation capability and thermal resistance when designing heat management strategies for high-density PCB layouts.

Single Zener Diodes Part Context

This part belongs to the MMSZ5221B through MMSZ5267B series, which offers a wide range of Zener voltages from 2.4 V to 75 V. All devices in this family share the same SOD-123 surface-mount package and general physical characteristics, differing primarily in their specific breakdown voltage and associated impedance values.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the MMSZ5237B designation in the SOD-123 package. Verify that substitute parts match the 8.2 V nominal voltage, ±5% tolerance, 500 mW power rating, and 8 Ω maximum Zener impedance to ensure functional equivalence.
