Single Zener Diodes Procurement Notes

Verify component authenticity by checking the cathode band marking code 'CM' on the SOD-123 package. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure storage conditions maintain thermal equilibrium as specified in the datasheet to preserve electrical parameter accuracy during handling and assembly processes.

Single Zener Diodes Selection Notes

Select this component when a precise 3.6 V reference is required in space-constrained designs. The SOD-123 footprint facilitates automated assembly for high-volume production. Consider the 350 mW power rating and thermal resistance limits for circuit layout. Verify that the operating environment remains within the specified -65°C to +150°C temperature range for reliable performance.

Single Zener Diodes Part Context

This part belongs to the CZRW4678-G through CZRW4717-G series, offering a wide Zener voltage range from 1.8 V to 43 V. All devices in this family share identical mechanical dimensions and packaging standards, allowing for design flexibility while maintaining consistent board space requirements across different voltage specifications.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the SOD-123 package, 3.6 V nominal voltage, and 350 mW power rating. Verify equivalent leakage current and capacitance values to ensure circuit compatibility. Cross-reference marking codes if visual identification is required for inventory management or assembly verification.
