Procurement Notes

Verify the specific suffix P1-7 against official Diodes Incorporated documentation to confirm package type and tape/reel specifications. Ensure the selected variant matches the required thermal performance and current rating for the target application. Cross-reference the datasheet revision date to guarantee compatibility with existing design parameters and regulatory compliance standards.

Selection Notes

Select this model when a fixed 25 mA output current is required for single-channel LED strings. The linear topology suits applications where simplicity and low component count are prioritized over high efficiency. Consider the 60 V maximum rating for series LED configurations. Verify that the operating temperature range meets the environmental demands of the final assembly.

Part Context

This component belongs to the AL5809 series of two-terminal LED drivers. The series offers various current options to suit different LED brightness requirements. The AL5809-25P1-7 specifically targets applications needing moderate current with high voltage tolerance. It complements other variants in the family by providing a balanced solution for general lighting tasks.

Replacement Considerations

Direct substitutes include other AL5809 variants with different current ratings, such as AL5809-15P1-7 or AL5809-50P1-7, if current adjustment is permissible. Ensure pin compatibility and package dimensions match when swapping within the same series.
