Procurement Notes

Verify the specific suffix against official datasheets, as variations may indicate different packaging or qualification levels. Confirm RoHS compliance status and AEC-Q101 automotive qualification requirements prior to integration. Ensure the ordering part number matches the exact package type and pinout configuration required for the target PCB footprint.

Selection Notes

Select this component for designs requiring fast switching speeds and high current handling in a through-hole format. The 400V rating suits general-purpose AC-DC conversion and intermediate bus applications. Evaluate thermal management needs based on the 16A continuous current rating and the specific ambient operating conditions of the final assembly.

Part Context

This device belongs to the MUR series of ultra-fast recovery rectifiers from Taiwan Semiconductor. It is designed to replace slower standard recovery diodes in high-efficiency power conversion systems. The product line emphasizes reduced switching losses and improved system efficiency through optimized silicon technology and robust packaging solutions.

Replacement Considerations

Direct substitutes include the MUR1640CTH variant which shares identical electrical specifications but may differ in marking or secondary source manufacturing details. Verify pin compatibility and thermal resistance parameters when cross-referencing with other manufacturers' 16A 400V super fast rectifiers.
