Applications

• Automotive exterior lighting systems
• Automotive interior illumination
• General LED lighting drivers

Procurement Notes

This component has reached End-of-Life (EOL) status and is no longer manufactured by Diodes Incorporated. Procurement should focus on identifying valid replacement parts rather than sourcing the original unit. Verify that any substitute component meets the same AEC-Q100 qualification requirements and maintains compatibility with existing PCB footprints and thermal management designs to ensure seamless integration into automotive lighting circuits.

Selection Notes

Engineers replacing this obsolete part must prioritize components with identical pinout configurations to minimize board redesign efforts. The substitute must support the required 1A output current and withstand input voltages up to 60V. Automotive qualification remains critical; therefore, selecting a part with AEC-Q100 certification is mandatory. Ensure the replacement offers comparable switching frequency characteristics to maintain electromagnetic interference performance within acceptable limits for the target application.

Part Context

The ZXLD1366QET5TA belongs to the ZXLD1366 family of LED drivers, which are optimized for efficient power conversion in lighting applications. This specific variant utilizes a TSOT-25 package, offering a compact solution for space-constrained designs. As an automotive-qualified device, it adheres to strict reliability standards required for vehicular electronics, distinguishing it from general-purpose industrial LED drivers within the broader product portfolio.

Replacement Considerations

Diodes Incorporated recommends the AL8862QFGEAW-7 as a manufacturer-approved substitute for this discontinued part number.
