Single Zener Diodes Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific ordering suffix matches the required packaging format, such as cut tape or reel, as these affect handling procedures. Ensure compliance with RoHS directives and check for any specific storage or moisture sensitivity level requirements prior to assembly.

Single Zener Diodes Selection Notes

Select this component when a precise 2.2 V reference is required in space-constrained designs. The EMD2 package offers a smaller footprint compared to standard SOD-123 variants. Consider the 150 mW power rating for thermal management in dense PCB layouts. Verify that the 120 µA leakage current meets the system's standby power constraints.
