Single Zener Diodes Procurement Notes

Verify the specific suffix UR-1 indicates the MELF package variant distinct from axial leaded versions. Confirm MIL-PRF-19500 compliance requirements match project specifications. Check for RoHS non-compliance status due to military grade construction. Validate manufacturer authenticity through authorized distribution channels to ensure quality assurance standards are met.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface-mount Zener diode is required for high-reliability environments. Ensure the 36V breakdown voltage aligns with circuit design needs. Consider the 1W power rating for thermal management calculations. Verify that the MELF footprint fits the available PCB space constraints compared to traditional axial packages.

Single Zener Diodes Part Context

This part belongs to the JANTX series of voltage regulator diodes, which offers enhanced performance over standard JAN grades. The BUR-1 suffix specifically denotes the MELF package style, differentiating it from the axial DO-41 variants. This series is widely used in aerospace and defense electronics where radiation hardness and thermal stability are critical operational parameters.

Single Zener Diodes Replacement Considerations

Direct substitutes include JANTX1N3033B-1 for axial mounting or JANTXV1N3033C-1 for tighter voltage tolerances. Ensure package compatibility when swapping between MELF and axial styles. Verify electrical parameter equivalence before implementation in existing designs.
