Single Zener Diodes Procurement Notes

Verify component authenticity by checking for the C5235B marking code on the DO-35 casing. Confirm RoHS compliance status via official manufacturer documentation before integration. Ensure ordering suffixes match specific plating requirements, as Pb-Free designations are mandatory for modern environmental standards. Validate datasheet revisions against procurement records to guarantee parameter accuracy.

Single Zener Diodes Selection Notes

Select this component when a 6.8 V reference with ±5% tolerance is required in an axial leaded package. The positive temperature coefficient indicates suitability for applications where voltage increases slightly with heat. Verify that the 500 mW power dissipation rating aligns with the thermal management capabilities of the target PCB layout and ambient operating conditions.
