• Integrated high-voltage internal switch capability
• Supports pulse-width modulation for brightness control

Applications

• LED lighting driver circuits
• General illumination systems
• Solid-state lighting applications

Procurement Notes

Verify the specific suffix 'QP1' against official manufacturer documentation to confirm quality grade and packaging specifications. Ensure compatibility with required thermal management solutions given the linear regulation method. Cross-reference datasheet revisions to confirm pinout consistency before finalizing procurement orders.

Selection Notes

Select this component when a simple two-wire connection is required for constant current regulation. It is suitable for designs needing integrated switching capabilities without external inductors. Consider the PowerDI-123-2 package size constraints and thermal dissipation requirements relative to the 40 mA load current.

Part Context

This part belongs to the AL5809 series of linear LED drivers from Diodes Incorporated. The series offers various fixed current options and packaging variants. The AL5809 family is designed for cost-effective, compact LED driving solutions requiring minimal external components.

Replacement Considerations

Check AL5809-40P1-7 for standard commercial grade equivalent. Verify AL5809-40S1-7 if SOD-123-2 packaging is acceptable instead of PowerDI-123-2.
