Procurement Notes

Verify the specific suffix '01' against the manufacturer's latest documentation to confirm current production status and any potential product change notifications. Ensure compatibility with the required SOT-89-5 footprint and thermal management requirements for the target application environment.

Selection Notes

Select this component for designs requiring a single-channel constant-current solution with an integrated high-voltage switch. It is suitable for input voltages up to 40V and requires support for either analog or pulse-width modulation dimming signals. Consider the SOT-89-5 package constraints for PCB layout and heat dissipation.

Part Context

This part belongs to the AL8861 series of LED drivers manufactured by Diodes Incorporated. The series includes variants such as AL8861Y-13 and AL8861WT-7, which share similar core functionalities but differ in packaging and specific electrical characteristics. The AL8861Y-13-01 specifically utilizes the SOT-89-5 package.

Replacement Considerations

AL8861Y-13 is a related variant within the same series. Verify pinout compatibility and electrical specifications before substitution.
