Procurement Notes
Verify the specific suffix E3/TR against official Microchip documentation to confirm RoHS compliance and tape-and-reel packaging configuration. Ensure the ordering part number matches the required voltage tolerance and package type. Cross-reference datasheet revisions to confirm electrical characteristics align with design requirements before procurement.
Selection Notes
Select this component when a 5.1 V Zener voltage with ±5% tolerance is required in a DO-35 axial package. Consider the 500 mW power rating and extended temperature range for suitability in harsh environments. Verify that the tape-and-reel packaging meets the manufacturing line's automation capabilities.
Part Context
This part belongs to the standard 1N4689 series of Zener diodes manufactured by Microchip Technology. The series offers various voltage options within the DO-35 package. The E3 designation typically indicates lead-free composition, while TR specifies the tape and reel shipping method for efficient handling.
Replacement Considerations
Consult Microchip's official cross-reference guides for verified substitutes. Generic equivalents may differ in leakage current, impedance, or thermal performance. Validate any alternative part against the original datasheet specifications to ensure functional compatibility.
