Single Zener Diodes Procurement Notes

Verify that the ordering code explicitly includes the HE3_A suffix to confirm AEC-Q101 qualification status. Ensure the C suffix is present to guarantee the required ±2% voltage tolerance. Confirm RoHS compliance and material categorization details against the latest Vishay documentation before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy is required alongside automotive-grade reliability. The SOD-123 package is suitable for space-constrained designs requiring efficient thermal management. Consider the specific dynamic resistance and leakage current characteristics at the operating point to ensure compatibility with the target circuit's sensitivity levels.

Single Zener Diodes Part Context

This part belongs to the MMSZ5225 to MMSZ5267 series of small-signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide Zener voltage range from 3.0 V to 75 V. The HE3_A suffix indicates an advanced lead-free glass passivation process designed specifically for automotive environments, distinguishing it from standard commercial grade variants.

Single Zener Diodes FAQ

What is the difference between the HE3_A and E3 suffixes?

The HE3_A suffix denotes AEC-Q101 qualification and lead-free construction suitable for automotive applications, whereas the E3 suffix indicates a standard commercial grade RoHS-compliant product without automotive qualification.

How does the 'C' suffix affect performance?

The 'C' suffix specifies a Zener voltage tolerance of ±2%, providing tighter voltage regulation compared to the 'B' suffix which allows for a wider ±5% tolerance.
