Single Zener Diodes Procurement Notes

Verify that the ordering suffix /TR indicates tape-and-reel packaging rather than bulk units. Confirm the specific revision level matches design requirements. Ensure procurement channels are authorized to guarantee authenticity for military-grade components. Check for any recent PCN notifications regarding assembly site or labeling changes.

Single Zener Diodes Selection Notes

Select this component when a 24 V Zener reference is required in a surface-mount form factor. The DO-213AA package suits automated assembly processes. Consider the 500 mW power rating for thermal management. Verify compatibility with existing PCB footprints for the DO-213AA case style.

Single Zener Diodes Part Context

This part belongs to the JAN1N970 series of Zener diodes produced by Microchip Technology. It is a qualified military version of the standard 1N970B device. The series provides stable voltage regulation for harsh environment applications requiring high reliability and strict parameter control.

Single Zener Diodes Replacement Considerations

Direct equivalents include JAN1N970BUR-1 (bulk) or JANTXV1N970BUR-1. Cross-reference with other manufacturers' 1N970B variants if pinout and electrical parameters match exactly.
