Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm packaging details. Confirm RoHS compliance status as it varies by production batch and region. Ensure the required tolerance aligns with the 'B' suffix designation. Validate lead solderability requirements prior to assembly.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V reference is required in an axial glass package. Consider the 500 mW power dissipation limit and thermal resistance constraints during circuit design. Evaluate the temperature coefficient for applications requiring stability across wide thermal ranges.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a broad range of voltages from 2.4 V to 75 V. These devices are designed for general-purpose voltage regulation and protection tasks in electronic circuits.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering equivalent 3.6 V Zener diodes in the DO-35 package. Verify that substitute parts meet the same 500 mW power rating and ±5% voltage tolerance specifications.
