Single Zener Diodes Procurement Notes

Verify the specific suffix designation when ordering, as variants such as -1PCT or -2PCT indicate different tolerance levels. Confirm package type availability, as surface mount equivalents like CDLL4582A exist. Check manufacturer documentation for RoHS compliance status and ensure the selected variant matches the required voltage tolerance for the target application circuit design.

Single Zener Diodes Selection Notes

Select this component when a stable 6.4 V reference is needed with minimal temperature coefficient. Compare against standard Zener diodes if tighter tolerance is required. Ensure the operating current aligns with the 4 mA test condition specified in the datasheet. Consider the DO-35 package constraints for PCB layout and verify that the maximum power dissipation rating suits the thermal environment of the final assembly.
