Single Zener Diodes Procurement Notes

Verify that the ordering code includes the B suffix to confirm the ±5% tolerance specification. Ensure the procurement quantity aligns with the manufacturer's minimum order requirements for the taped reel packaging configuration. Confirm compliance with material categorization standards as defined in the official Vishay documentation before finalizing acquisition.

Single Zener Diodes Selection Notes

Select this component when a precise 3 V reference is required with moderate tolerance constraints. The DO-35 package facilitates through-hole mounting on printed circuit boards. Consider the thermal resistance characteristics if operating near the maximum power dissipation limit. Verify that the application environment remains within the specified storage and operating temperature ranges.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes. The series covers a wide Zener voltage range from 2.4 V to 75 V. Variants are available in different tolerance grades and alternative packages such as MiniMELF and SOT-23. The 1N5225 designation specifically targets the 3 V segment of this extensive product line.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering equivalent 3 V Zener diodes in the DO-35 package. Verify that substitute components match the 500 mW power rating and ±5% tolerance specifications. Ensure the replacement maintains compatible thermal resistance and forward voltage characteristics for the specific circuit design.
