Single Zener Diodes Procurement Notes

Verify that the specific ordering code matches the required tolerance suffix 'A' for ±5% accuracy. Confirm RoHS compliance status and ensure the package type aligns with the intended PCB footprint. Validate that the manufacturer's datasheet specifications meet the thermal and electrical requirements of the final assembly environment before procurement.

Single Zener Diodes Selection Notes

Select this component when a 6.2 V reference is needed in a compact SMA package. Ensure the circuit design accommodates the 1 W power rating and the specific dynamic impedance characteristics. Consider the AEC-Q101 qualification if the application involves automotive environments or requires enhanced reliability standards compared to commercial grade parts.

Single Zener Diodes Part Context

This part belongs to the SML4728 through SML4764A series of surface mount Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of nominal voltages from 3.3 V to 100 V in the standard DO-214AC package. The 'A' suffix indicates tighter voltage tolerance compared to the standard ±10% configuration.

Single Zener Diodes Replacement Considerations

Direct substitutes include other Vishay SML4735 variants such as SML4735-E3/5A or SML4735HE3/5A, provided the voltage tolerance and package dimensions are compatible.
