Single Zener Diodes Procurement Notes

Verify the specific qualification level (JAN, JANTX, JANTXV, or JANS) required for your application, as this affects performance and availability. Confirm RoHS compliance status, noting that commercial versions may differ from mil-qualified parts. Ensure the ordering suffix matches the desired packaging and material specifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select the 1N4134-1 when a precise 91 V reference is needed in harsh environments requiring radiation hardness. Consider the thermal resistance and derating curves if operating near the maximum temperature limits. Verify that the package dimensions fit the PCB layout constraints for the DO-35 style housing.
