Single Zener Diodes Procurement Notes

Verify the specific suffix UR-1 against official Microchip documentation to confirm the leadless MELF package configuration. Ensure that the required tolerance and temperature ratings align with the system specifications before procurement. Cross-reference the manufacturer part number with the latest datasheet revisions to avoid obsolete or superseded variants.

Single Zener Diodes Selection Notes

Select this component when a robust surface-mount Zener diode is required for high-temperature environments. The MELF package offers advantages in space-constrained designs compared to traditional axial leads. Consider the 1 W power rating and 4.3 V breakdown voltage as primary selection criteria for shunt regulator topologies.

Single Zener Diodes Part Context

This component belongs to the 1N3821A through 1N3828 series of Zener diodes produced under MIL-PRF-19500/115 standards. The series includes various voltage options packaged in both through-hole and surface-mount configurations. The UR-1 suffix specifically denotes the surface-mount variant within this military-grade lineup.

Single Zener Diodes Replacement Considerations

Compatible substitutes include JAN1N3824AUR-1 and JANTXV1N3824CUR-1, provided they meet the same MIL-PRF-19500/115 specifications and package dimensions.
