Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options and compliance status. Confirm that the requested variant matches the exact package type and tolerance requirements for your design. Ensure all environmental regulations are met by checking the official datasheet specifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 4.7 V reference is required in a compact surface-mount footprint. The ±5% tolerance offers a balance between cost and precision for general-purpose regulation tasks. Consider the low leakage current and defined impedance characteristics for sensitive analog signal conditioning or reference voltage generation applications.

Single Zener Diodes Part Context

This part belongs to the CMPZ5221B through CMPZ5267B series of surface-mount silicon Zener diodes. All devices in this family share the same SOT-23 mechanical outline and 350 mW power rating, differing primarily in their specific Zener voltage ratings and corresponding marking codes. The series is designed to provide standardized voltage regulation solutions across a wide spectrum of nominal voltages.
