Single Zener Diodes Procurement Notes

Verify that the specific part number suffix matches the required tolerance grade and packaging configuration. Confirm RoHS compliance status and lead-free finish requirements prior to ordering. Ensure the procurement documentation aligns with the manufacturer's latest datasheet specifications for electrical characteristics and mechanical dimensions.

Single Zener Diodes Selection Notes

Select this component when a 6.8 V regulation point is required in space-constrained designs utilizing the SOD-123 footprint. Consider the 500 mW power dissipation limit and thermal resistance values when designing heat management strategies. Evaluate the 5% voltage tolerance against circuit sensitivity requirements to ensure adequate performance margins under varying operating conditions.

Single Zener Diodes Part Context

This device belongs to the MMSZ52xxxT1G series of Zener voltage regulators manufactured by onsemi. The series offers a wide range of breakdown voltages from 2.4 V to 110 V in the same surface-mount package format. These components serve as alternatives to traditional leaded packages, enabling higher density PCB layouts while maintaining reliable voltage regulation capabilities across industrial temperature ranges.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering equivalent SOD-123 packaged Zener diodes with 6.8 V nominal voltage and 500 mW power ratings. Verify pinout compatibility and physical dimensions before substitution. Ensure replacement parts meet or exceed the original electrical parameters including impedance, leakage current, and ESD ratings.
