Single Zener Diodes Procurement Notes

Verify that the specific ordering code matches the required tolerance suffix and qualification level. Confirm that the component meets the exact electrical specifications needed for the target application environment. Ensure compliance with RoHS directives and material categorization requirements as defined by the manufacturer.

Single Zener Diodes Selection Notes

Select this component when a precise 47 V reference is required within a compact SOD-123 footprint. The ±2% tolerance makes it suitable for applications demanding tighter voltage accuracy than standard commercial grades. Consider the AEC-Q101 qualification if the design targets automotive or high-reliability industrial systems.

Single Zener Diodes Part Context

This part belongs to the MMSZ5225 to MMSZ5267 series of small signal Zener diodes manufactured by Vishay. The series covers a wide range of Zener voltages from 3.0 V to 75 V. The 'C' suffix indicates a tighter ±2% tolerance compared to the standard ±5% 'B' suffix variants. The HE3_A suffix denotes RoHS compliance and AEC-Q101 qualification.
