Single Zener Diodes Procurement Notes

Verify the specific suffix against official documentation to confirm tolerance and RoHS status. Ensure the ordering code matches the required qualification level. Confirm tape and reel specifications if bulk packaging is not acceptable. Cross-reference the datasheet revision date to validate electrical parameters before procurement.

Single Zener Diodes Selection Notes

Select this component when a 51 V Zener reference is required in a leadless surface mount form factor. Consider the DO-213AB outline for space-constrained designs. Evaluate thermal resistance and derating curves for high-temperature environments. Verify that the 5% voltage tolerance aligns with circuit requirements.

Single Zener Diodes Part Context

This part belongs to the 1N3016BUR-1 through 1N3045BUR-1 series of 1 Watt Surface Mount Zener Diodes. These devices serve as surface mount equivalents to JEDEC registered axial-leaded counterparts. The series provides a wide selection of voltages from 6.8 V to 110 V in a single package type.
