Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct tolerance and packaging specifications. Confirm that the AEC-Q101 qualification status meets your project's automotive reliability requirements. Check for any recent lifecycle notices or obsolescence warnings directly from Vishay before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a precise 8.2 V reference is required in space-constrained designs utilizing the SOD-323 footprint. The ±2% tolerance makes it suitable for applications demanding tighter voltage accuracy than standard ±5% variants. Ensure the circuit design accounts for the 200 mW power dissipation limit and the specified thermal resistance characteristics.

Single Zener Diodes Part Context

This part belongs to the BZX384-V-Series of small-signal Zener diodes from Vishay. The series utilizes silicon planar technology and offers various voltage grades according to the E24 standard. The 'B' designation indicates the tighter ±2% tolerance variant, distinguishing it from the standard 'C' tolerance parts within the same family.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same Vishay lineup include other BZX384B8V2 variants with different packaging codes, such as BZX384B8V2-HE3_A08. Cross-manufacturer replacements require matching the 8.2 V Zener voltage, 200 mW power rating, SOD-323 package, and AEC-Q101 qualification.
