Single Zener Diodes Procurement Notes

Verify the specific revision level and lot traceability documentation upon order confirmation. Ensure that the procurement channel is authorized to handle JANTX qualified components. Confirm that the packaging meets the required handling standards for sensitive military-grade semiconductors. Request full material certification if the application demands strict compliance with defense specifications.

Single Zener Diodes Selection Notes

Select this component when a surface-mount Zener diode with verified military reliability is required. The internal metallurgical bond distinguishes it from standard bonded or non-bonded variants. Consider the DO-213AA footprint constraints during PCB layout. Verify that the 27 V regulation point aligns with the circuit's reference voltage requirements.

Single Zener Diodes Part Context

This device belongs to the 1N4099UR-1 through 1N4135UR-1 series of glass surface mount Zener regulators. These parts are designed as surface-mount equivalents to traditional axial-leaded JEDEC registered Zener diodes. The series offers various voltage options within the 1.8 to 100 V range, maintaining consistent physical dimensions across the family for standardized mounting solutions.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JANTX qualified versions of the 1N4118 series, such as JANTX1N4118C-1 or JANTXV1N4118D-1, provided the tolerance and package match. Non-military equivalents like the standard 1N4118DUR-1 lack the required qualification level.
