Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'C' suffix to confirm the ±2% tolerance specification. Ensure the 'TAP' designation matches the required taped reel packaging format. Confirm compliance with material categorization definitions via the manufacturer's documentation before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical due to its tighter tolerance compared to standard variants. The DO-35 through-hole package facilitates easy integration into traditional circuit boards. Evaluate the thermal resistance requirements against the 500 mW power dissipation limit for the specific application environment.

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 Zener voltage range from 2.4 V to 75 V. The 1N5251 variant specifically targets the 22 V segment of this lineup, providing a standardized solution for mid-range voltage reference applications.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 22 V Zener diodes in the DO-35 package. Verify that substitute components meet the same ±2% tolerance and 500 mW power rating specifications to ensure functional compatibility.
