Current Regulation - Diodes, Transistors Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm RoHS compliance status and specific packaging options such as bulk or reel configurations prior to ordering. Ensure supply chain integrity to prevent counterfeit components from entering production lines.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a stable 4.73 mA current is required without complex circuitry. Consider the 100 V peak voltage rating for high-voltage applications. Evaluate thermal management requirements given the 10 mW power dissipation limits inherent to the small form factor.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the CDLL series of current regulator diodes produced by Microchip Technology. It shares the same functional characteristics and physical package dimensions as the CDLL5313e3 variant, differing primarily in environmental compliance markings rather than electrical performance specifications.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include other 4.73 mA current regulator diodes in the DO-213AB package. Verify that alternative parts match the 2.75 V limit voltage and 100 V peak voltage ratings to ensure circuit compatibility.
