Single Zener Diodes Procurement Notes

Verify the specific suffix G3-18 against the official Vishay datasheet to confirm lead-free compliance and reel packaging specifications. Ensure the ordering part number matches the required ±5% tolerance designation (C) rather than tighter tolerance variants. Cross-reference the manufacturer's latest revision history to confirm component status and any potential obsolescence notices before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a 3 V Zener reference is needed in space-constrained designs utilizing the SOD-323 footprint. Consider the 200 mW power rating and thermal resistance limits for high-density PCB layouts. Verify that the 95 Ohm dynamic impedance meets the noise and regulation requirements of the target application circuit compared to lower impedance alternatives.

Single Zener Diodes Part Context

This part belongs to the BZX384-V-Series of small signal Zener diodes from Vishay. The series offers various voltage options graded to international standards, all housed in the same SOD-323 plastic case. The product line emphasizes lead-free construction and environmental compliance, serving as a standard discrete solution for general-purpose voltage regulation tasks across consumer and industrial electronics.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same family include BZX384C3V0-E3-18 and BZX384C3V0-HE3-18, which share identical electrical parameters and mechanical dimensions. Other manufacturers producing equivalent 3 V Zener diodes in SOD-323 packages may serve as functional replacements if pinout compatibility and thermal ratings are verified.
