Single Zener Diodes Procurement Notes

Verify the authenticity of the component through authorized MCC distributors or direct procurement channels to avoid counterfeit parts. Confirm that the ordering suffix matches the specific tape-and-reel packing configuration required for your manufacturing line. Ensure compliance with environmental regulations such as RoHS and REACH based on the HE3 designation.

Single Zener Diodes Selection Notes

Select this component when a precise 4.7 V reference with high accuracy is required in compact designs. The ±2% tolerance makes it suitable for applications demanding strict voltage stability. Consider the SOT-23 package constraints regarding thermal dissipation and ensure the operating environment stays within the specified temperature limits.

Single Zener Diodes Part Context

This part belongs to the BZX84 series of low-power Zener diodes from Micro Commercial Components. The series offers various breakdown voltages ranging from 2.4 V to 36 V. The 'B' suffix indicates the ±2% tolerance grade, while 'HE3' denotes the halogen-free and lead-free formulation. It is designed for general-purpose voltage regulation in consumer and industrial electronics.

Single Zener Diodes Replacement Considerations

Direct substitutes include other BZX84B4V7 variants from different manufacturers, provided they match the SOT-23 package and ±2% tolerance. Verify that alternative components meet the same AEC-Q101 qualification if automotive use is intended.
