Single Zener Diodes Procurement Notes

Verify component authenticity by checking for the 'C5228B' marking code on the device body. Confirm RoHS compliance status via official manufacturer documentation. Ensure ordering suffixes match specific plating requirements, such as PBFREE for lead-free specifications. Validate that the DO-35 package dimensions align with existing PCB footprints before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 3.9 V reference is required in low-power applications. The ±5% tolerance suits general-purpose regulation tasks. Consider the 500 mW power rating for thermal management in enclosed environments. Verify that the negative temperature coefficient near -0.060 %/°C is acceptable for the target circuit stability requirements.
