Single Zener Diodes Procurement Notes

Verify the specific suffix E3-18 to confirm lead-free compliance and reel packaging configuration. Ensure the ordering part number matches the exact ±2% tolerance variant required for the design. Cross-reference the manufacturer datasheet for thermal derating curves and absolute maximum ratings before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 56 V reference with strict ±2% accuracy is necessary. The SOD-323 package suits automated surface-mount assembly processes. Consider the 200 mW power rating and thermal resistance limits during PCB layout planning to ensure reliable operation under continuous load conditions.

Single Zener Diodes Part Context

This part belongs to the BZX384 series of low-power voltage regulator diodes. The series offers normalized voltages from 2.4 V to 75 V in small plastic SMD packages. The 'B' designation indicates the tighter ±2% tolerance band compared to the standard ±5% variants, providing enhanced stability for sensitive analog and digital control circuits.

Single Zener Diodes Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include BZX384B56-G3-18 and BZX384B56-G3-08. These alternatives share identical electrical specifications and package dimensions. Verify that the replacement maintains the same ±2% tolerance and SOD-323 footprint compatibility.
