Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' confirms tape-and-reel packaging configuration. Ensure the component meets RoHS directives as indicated by the 'e3' designation. Confirm that the DO-213AA footprint matches the target PCB design constraints. Validate that the 500 mW power rating aligns with the thermal management capabilities of the final application environment.

Single Zener Diodes Selection Notes

Select this component when a precise 9.1 V regulation point is required in space-constrained designs. The wide operating temperature range makes it suitable for harsh environments where standard silicon devices may fail. Consider the low leakage current for high-impedance circuit applications. The surface-mount format facilitates efficient placement in high-volume manufacturing processes.

Single Zener Diodes Part Context

This part belongs to the CDLL46xx series of Zener diodes from Microchip Technology. The series offers various voltage options in the same DO-213AA package form factor. The 'e3' suffix typically denotes lead-free composition compliant with environmental standards. This family is engineered for reliability in demanding electronic systems.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 9.1 V Zener voltage, 500 mW power rating, and DO-213AA package. Verify equivalent electrical parameters such as leakage current and impedance. Cross-reference with other manufacturers offering compatible SMD Zener diodes if supply chain constraints exist.
