Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm exact electrical tolerances and packaging variations. Ensure the procurement channel provides valid traceability certificates. Confirm that the component matches the required LP4 mounting specifications for your thermal management design before finalizing orders.
Selection Notes
Select this component for applications requiring high voltage blocking and substantial current capacity in a compact footprint. Compare the 290 ns reverse recovery time against system switching frequencies to ensure adequate performance margins. Evaluate the thermal resistance of the LP4 package relative to your heatsink design to maintain safe operating junction temperatures under continuous load conditions.
Part Context
This part belongs to the APTDF400 series of high-voltage power diodes from Microchip Technology. The series is designed for robust performance in industrial power electronics. The LP4 package provides a standardized interface for mounting on cold plates or heatsinks, facilitating integration into larger power modules and discrete high-current rectifier assemblies.
Replacement Considerations
Consult official Microchip substitution guides for verified equivalents. Cross-reference pinouts and thermal characteristics carefully when considering alternatives from other manufacturers to ensure compatibility with existing PCB layouts and cooling solutions.
