Single Zener Diodes Procurement Notes

Verify the specific suffix /DG/B3,23 against official Nexperia documentation to confirm tape-and-reel packaging details and RoHS compliance status. Ensure the component matches the standard BZX84-C series electrical specifications before procurement.

Single Zener Diodes Selection Notes

Select this component when a 18 V reference with ±5% accuracy is required in space-constrained designs. The SOD-323 package offers higher power dissipation than standard SOT-23 variants, supporting up to 550 mW thermal handling.

Single Zener Diodes Part Context

This part belongs to the Nexperia BZX84 series of low-power Zener diodes. The series provides normalized breakdown voltages from 2.4 V to 75 V in E24 ranges, offering standardized options for various voltage regulation needs in consumer and industrial electronics.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' Zener diodes in the SOD-323 package with 18 V nominal voltage, 550 mW power rating, and ±5% tolerance. Verify pinout compatibility and thermal characteristics during substitution.
