Single Zener Diodes Procurement Notes

Verify the ordering code matches MMSZ5237C-E3-08 to ensure the correct ±2% tolerance and SOD-123 packaging. Confirm RoHS compliance status if required by specific manufacturing standards. Check that the supplier provides documentation referencing document number 86344 for accurate electrical specifications. Ensure storage conditions adhere to the specified moisture sensitivity level and temperature ranges to maintain component integrity before assembly.

Single Zener Diodes Selection Notes

Select this component when a precise 8.2 V reference is needed with tighter than standard tolerance. The SOD-123 package suits space-constrained designs compared to larger axial leads. Consider the 500 mW power rating for thermal management in enclosed environments. Verify that the operating temperature range meets the environmental requirements of the target application.

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 offers various Zener voltages from 3.0 V to 75 V in the SOD-123 surface-mount package. The 'E3' suffix indicates lead-free termination, while '08' denotes the 8 mm tape reel packaging format for automated placement.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering SOD-123 packaged Zener diodes with 8.2 V nominal voltage and ±2% tolerance. Verify pinout compatibility and thermal resistance values to ensure equivalent performance in existing footprints.
