Single Zener Diodes Procurement Notes

Verify the specific ordering suffix HE3_A-08 against official Vishay documentation to confirm AEC-Q101 qualification status. Ensure the required ±2% tolerance aligns with design specifications. Confirm that the SOD-123 package dimensions match the target PCB footprint requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical due to its ±2% tolerance. The AEC-Q101 qualification makes it suitable for automotive environments requiring high reliability. Consider the 500 mW power dissipation limit and thermal resistance characteristics during circuit layout to ensure stable operation across the specified temperature range.

Single Zener Diodes Part Context

This part belongs to the MMSZ5225 to MMSZ5267 series of small signal Zener diodes. The 'C' suffix indicates the tighter ±2% voltage tolerance compared to the standard ±5% 'B' suffix variants. The 'HE3_A' designation identifies the specific lead-free, automotive-grade version within the broader product family.
