AL5890-30D-13

Overview

The AL5890-30D-13 is a constant current LED driver manufactured by Diodes Incorporated. It utilizes a boost topology to regulate output current at 30 mA. The device supports an input voltage range from 7 V to 400 V and can drive loads up to 400 V. It operates within a frequency of 20 kHz and features thermal foldback protection. The component is housed in a TO-252-3 package, suitable for surface mount installation. It functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

• Boost topology enables high-voltage LED driving with minimal external components
• Integrated thermal foldback protection ensures operational safety under stress
• Two-pin solution design simplifies circuit layout and reduces bill of materials

Applications

• LED lighting systems requiring high forward voltage
• Industrial illumination applications
• Automotive exterior lighting modules

Procurement Notes

Verify the specific suffix D-13 against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status directly with Diodes Incorporated documentation prior to integration. Ensure the supplier provides valid traceability records for automotive or industrial qualification requirements if applicable.

Selection Notes

Select this part when a linear driver cannot handle the voltage drop or power dissipation. The boost architecture allows operation with input voltages significantly lower than the LED string voltage. Compare against the AL5890-15P1-13 for current requirements and PowerDI packages versus the TO-252-3 thermal performance needs.

Part Context

This component belongs to the AL5890 series of constant current LED drivers. It shares functional similarities with other parts in the family but differs in output current rating and physical packaging. The series targets cost-sensitive lighting designs requiring robust regulation without complex control loops.

Replacement Considerations

Public confirmed substitutes include AL5890-15P1-13 for lower current needs and AL5890-30QP1-7 for automotive qualified linear alternatives. Verify pinout compatibility and thermal characteristics before substitution.
