Single Zener Diodes Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm exact manufacturing lot specifications and compliance status. Ensure that the required packaging format aligns with production needs, as reel configurations may vary. Cross-reference the part number with authorized distributors to validate authenticity and current availability status before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a 28 V regulation point is required within a low-power constraint. The DO-35 package suits designs prioritizing compact through-hole assembly over surface mount alternatives. Evaluate thermal management requirements carefully, as the 0.25 W dissipation limit restricts usage in high-current scenarios compared to higher-wattage variants.

Single Zener Diodes Part Context

This device belongs to the established 1N47xx series of Zener diodes manufactured by Microchip Technology. The series offers standardized voltage ratings for consistent performance across various industrial and commercial electronics. The TR suffix typically indicates tape and reel packaging, facilitating automated insertion processes in high-volume manufacturing environments.

Single Zener Diodes Replacement Considerations

Consult official Microchip substitution guides for verified equivalents. Generic replacements must match the 28 V Zener voltage, 0.25 W power rating, and DO-35 package dimensions to ensure mechanical and electrical compatibility without circuit redesign.
