Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm packaging type and tolerance class. Ensure that the required electrical parameters align with the datasheet specifications before finalizing procurement decisions. Cross-reference the component marking with the manufacturer's latest release notes.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation within a narrow tolerance band is required. The DO-35 package provides a reliable through-hole mounting solution suitable for standard PCB layouts. Evaluate the thermal dissipation requirements to ensure the operating conditions remain within the specified absolute maximum ratings.

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 wide range of nominal voltages from 2.4 V to 75 V. The 'C' suffix specifically denotes the tighter ±2% voltage tolerance variant compared to the standard ±5% version.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1N5228 variants such as 1N5228B or 1N5228TAP, provided the tolerance requirements are met. Verify that any substitute maintains the same DO-35 footprint and meets the 500 mW power dissipation rating.
