Procurement Notes

Verify the specific suffix E1-AY against the manufacturer's current datasheet to ensure compatibility with your design requirements. Confirm that the TO-252-7 package dimensions match your PCB footprint. Check for any recent Product Change Notifications (PCNs) regarding material or process updates. Ensure the operating voltage and thermal management strategies align with the specified 150°C junction limit. Validate that the component meets all necessary automotive quality standards required for your final assembly.

Selection Notes

Select this IPD when a single-channel high-side switch with low conduction loss is required. Consider its 28V maximum rating for standard automotive electrical systems. Evaluate the thermal performance given the 16mΩ resistance under expected load currents. Compare the 200µs switching times against system response requirements. Ensure the TO-252-7 package fits within the available board space constraints.

Part Context

This component belongs to the UPD16602x series of Intelligent Power Devices from Renesas. These devices are engineered for high-reliability applications in automotive and industrial sectors. The series typically offers integrated protection features and robust packaging solutions. The UPD166024 variant specifically targets single-load control scenarios requiring high efficiency and durability.

Replacement Considerations

Check for direct substitutes within the UPD16602x family, such as the UPD166024T1K-E2-AY, ensuring pinout and electrical specifications remain compatible. Verify if alternative packages like PowerHSSOP are acceptable for your design. Consult Renesas documentation for any recommended cross-reference parts that meet identical thermal and electrical criteria.
