Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix 'e3' indicates lead-free compliance when sourcing. Confirm the manufacturer is Microchip Technology, as similar part numbers may exist from other vendors. Ensure the DO-213AB-2 package footprint matches the design layout. Check for any specific handling requirements associated with glass-encapsulated semiconductor devices during assembly.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current value near 4.73 mA is required without complex feedback loops. Consider the 100 V peak voltage rating to ensure it exceeds the maximum potential drop across the regulated branch. Verify that the thermal management capabilities support operation at temperatures up to 175°C if used in high-heat environments.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the CDLL5313 series of current regulator diodes produced by Microchip Technology. These devices are designed to replace resistors in applications where constant current is necessary. The E3 suffix typically denotes environmental compliance, specifically lead-free manufacturing processes aligned with international standards.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct replacements must match the 4.73 mA current rating and DO-213AB-2 package. Cross-reference with other manufacturers' CRD offerings in the SOD-80 package. Verify impedance characteristics if precise line regulation is critical for the specific application.
