Ensure the requested part number matches the exact electrical specifications required for the design. Cross-reference manufacturer datasheets to validate availability and production lifecycle status before finalizing procurement plans.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current source is required in a surface-mount application. Verify that the 4.73 mA regulation value aligns with the target circuit requirements. Confirm that the 100 V peak voltage rating exceeds the maximum potential voltage across the diode in the intended operational environment.

Current Regulation - Diodes, Transistors Part Context

This device belongs to the CDLL series of current regulator diodes produced by Microchip Technology. It shares functional similarities with other MELF-packaged regulators but is distinct due to its specific 4.73 mA rating and military-grade temperature capabilities. It serves as a solid-state alternative to resistor-based current limiting solutions.

Current Regulation - Diodes, Transistors Replacement Considerations

Consult official substitution guides for compatible current regulator diodes with matching 4.73 mA ratings and DO-213AB packages. Verify pinout compatibility and thermal characteristics before replacing existing components in established designs.
