Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to confirm compliance requirements. The PBFREE designation indicates lead-free plating options are available upon request by adding the appropriate suffix during procurement. Ensure the component matches the required marking code M8 for correct identification on the assembly line.

Single Zener Diodes Selection Notes

Select this component when a stable 4.7 V reference is needed in a small form factor. The SOD-523 case offers space efficiency while maintaining thermal resistance of 500 °C/W. Consider the 250 µA test current requirement for biasing networks and ensure the circuit design accommodates the specified 1.0 Ω impedance limit.

Single Zener Diodes Part Context

This part belongs to the CMOZ1L8 through CMOZ47L series of low-level silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a voltage range from 1.8 V to 47 V, all sharing the same SOD-523 package and 250 mW power dissipation rating. The CMOZ4L7 specifically targets the mid-range voltage segment of this lineup.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include CMOZ4L3 (4.3 V) and CMOZ5L1 (5.1 V). Verify that any replacement maintains the SOD-523 footprint and meets the 250 mW power dissipation requirement.
