Procurement Notes

Verify the specific suffix requirements against the manufacturer's datasheet to ensure correct tolerance and packaging options. Confirm that the DO-213AB package dimensions match your PCB footprint layout. Check for RoHS compliance status if required by your assembly specifications, as non-compliant versions exist within this series.

Selection Notes

Select this component when a 1W surface mount Zener diode with hermetic sealing is required. Ensure the 36V breakdown voltage aligns with your circuit regulation needs. Consider the thermal resistance values for derating calculations based on your specific board mounting conditions and ambient temperature constraints.

Part Context

This part belongs to the 1N4728UR through 1N4764AUR series of surface mount glass Zener diodes. It serves as the DO-213AB equivalent to the axial-leaded 1N4753A registration. The series offers various tolerance options and screening levels for military and aerospace use cases.

Replacement Considerations

Direct electrical equivalents include the 1N4753AUR and MLL4753A. Verify package compatibility and tolerance specifications before substitution.
