Single Zener Diodes Procurement Notes

Verify the specific package configuration and handling requirements for bare die components before procurement. Confirm compliance with RoHS directives and export control classifications (EAR99) relevant to your region. Ensure that the supplier provides official datasheets to validate the 500 mW power rating and 47 V Zener voltage parameters for your design.

Single Zener Diodes Selection Notes

Select this component when a discrete 47 V Zener reference is required in a surface-mount format. The bare die construction allows for direct attachment to substrates, reducing parasitic effects compared to packaged equivalents. Consider the 500 mW power dissipation limit and the ±5% voltage tolerance when designing the surrounding circuitry to ensure stable operation under varying load conditions.

Single Zener Diodes Part Context

This part belongs to the family of single Zener diodes produced by Microchip Technology. It serves as a fundamental voltage regulation element within the broader portfolio of discrete semiconductor devices. The CD5261B complements other voltage regulator products by offering a specific 47 V breakdown voltage in a form factor optimized for advanced packaging technologies.

Single Zener Diodes Replacement Considerations

Consult official Microchip documentation for qualified substitute part numbers. Verify that any alternative component matches the 47 V Zener voltage, 500 mW power rating, and ±5% tolerance. Ensure compatibility with the intended surface-mount or bare die application environment.
