Single Zener Diodes Procurement Notes

Verify that the specific JAN prefix indicates full military qualification rather than commercial grade. Confirm the DO-213AA package orientation matches the design footprint. Ensure the ±2% tolerance aligns with circuit requirements. Check for RoHS compliance status if required by project specifications. Validate the manufacturer lot traceability for mission-critical deployments.

Single Zener Diodes Selection Notes

Select this component when a 47 V reference is required in a compact surface-mount format. The wide operating temperature range supports harsh environment deployment. Compare against through-hole alternatives if board space permits lower profile requirements. Consider the higher cost associated with military qualification levels versus commercial variants.
