Single Zener Diodes Procurement Notes

Verify the specific ordering code MMSZ4682-G3-18 against official Vishay documentation to ensure correct packaging and specifications. Confirm that the SOD-123 package dimensions and soldering conditions align with your assembly process requirements. Check for any regional technical support contacts if further validation is needed before procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 2.7 V reference is required in a compact SOD-123 footprint. Ensure the operating environment stays within the specified temperature range of -55 °C to +150 °C. Consider the low test current of 0.05 mA for low-power design constraints and verify that the thermal resistance values suit your board layout.

Single Zener Diodes Part Context

This part belongs to the MMSZ4681-G to MMSZ4717-G series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series covers a wide range of Zener voltages from 2.4 V to 43 V, all sharing similar package and electrical characteristics. The MMSZ4682 variant specifically targets the lower end of this voltage spectrum.

Single Zener Diodes Replacement Considerations
