Single Zener Diodes Procurement Notes

Verify that the ordering code matches BZX84B36-HE3_A-18 exactly to ensure the correct combination of 36 V nominal voltage, ±2% tolerance, and AEC-Q101 qualification. Confirm the suffix indicates taped units per reel as required by the assembly process. Cross-reference the datasheet revision to ensure compliance with current RoHS and material categorization standards.

Single Zener Diodes Selection Notes

Select this component when a precise 36 V reference is needed in space-constrained designs requiring automotive-grade reliability. The ±2% tolerance distinguishes it from standard commercial grades. Ensure the application current aligns with the 2 mA test condition to maintain accuracy within the specified dynamic resistance limits.

Single Zener Diodes Part Context

This part belongs to the BZX84 series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series utilizes silicon planar technology and offers a wide range of standardized voltages. The specific HE3_A suffix denotes a lead-free, halogen-free variant that meets strict automotive qualification standards.

Single Zener Diodes Replacement Considerations

Substitutes must match the 36 V nominal voltage, ±2% tolerance, and SOT-23 package. Verify that any alternative component holds equivalent AEC-Q101 certification if automotive use is intended.
