Single Zener Diodes Procurement Notes

Verify the authenticity of the component by checking for the cathode band marking and type number as specified in the datasheet. Ensure the ordering suffix matches the required packaging format, such as tape and reel or bulk, to align with assembly requirements. Confirm compliance status regarding lead-free finishes and RoHS directives before procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 2.5 V reference is needed with tight tolerance. Consider the negative temperature coefficient for thermal stability in low-voltage applications. Verify that the through-hole DO-35 package fits the board layout constraints and that the 500 mW power rating accommodates the expected operating current without excessive derating.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5267B series of 500 mW Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 2.4 V to 75 V, all sharing similar physical dimensions and general electrical characteristics defined by the DO-35 package standard.

Single Zener Diodes Replacement Considerations

Compatible equivalents include the onsemi 1N5222B and Microchip Technology 1N5222B. These parts share the same nominal voltage, power dissipation, and package style, allowing for potential pin-compatible substitution if electrical tolerances align with design requirements.
