Single Zener Diodes Procurement Notes

Verify that the ordering suffix UR-1 corresponds specifically to the DO-213AB MELF package variant. Confirm compliance with MIL-PRF-19500/115 requirements for your specific quality level. Ensure the supplier provides traceability documentation consistent with military procurement standards. Check for any specific handling instructions related to the hermetic seal integrity during assembly.

Single Zener Diodes Selection Notes

Select this component when a hermetic surface-mount Zener diode is required for high-reliability applications. The DO-213AB package offers a compact footprint suitable for space-constrained designs. Consider the 1 W power rating and 5.1 V nominal voltage for appropriate circuit matching. The wide temperature range makes it suitable for extreme environmental conditions where standard commercial parts may fail.

Single Zener Diodes Part Context

This part belongs to the JAN1N3826 series of silicon voltage regulators. It is functionally equivalent to the through-hole 1N3826A but adapted for surface-mount technology via the MELF package. The series includes variants with different tolerances, such as the JAN1N3826DUR-1 which offers tighter 1% tolerance. The UR-1 suffix denotes the specific leadless glass encapsulation style used in this generation of military-grade components.

Single Zener Diodes Replacement Considerations

JAN1N3826DUR-1 offers a tighter 1% voltage tolerance while maintaining similar electrical characteristics. JANTXV1N3826AUR-1 provides an alternative from VPT Inc with comparable performance metrics. Verify pinout compatibility and thermal management requirements when substituting with these variants.
