• Clamping applications

Single Zener Diodes Procurement Notes

Verify that the component matches the specific Vishay datasheet document number 86348. Confirm the suffix 'C' indicates the required ±2% tolerance rather than the standard ±5%. Ensure the ordering code includes the '-G3-08' designation to guarantee compliance with environmental directives and correct reel packaging specifications.

Single Zener Diodes Selection Notes

Select this component when a precise 3.9 V reference is needed in a compact SMD footprint. The low dynamic resistance supports effective clamping performance. Consider the negative temperature coefficient for thermal stability requirements. Verify that the 500 mW power dissipation rating aligns with the expected operating conditions and ambient temperatures of the target circuit design.

Single Zener Diodes Part Context

This part belongs to the MMSZ5225-G to MMSZ5267-G series of small signal Zener diodes. The series covers a wide range of voltages from 3.0 V to 75 V. The MMSZ5228 variant specifically targets the lower end of the voltage spectrum, providing reliable regulation for low-voltage logic and analog signal conditioning tasks within the SOD-123 form factor.
