Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging type, such as Tape & Reel (TR) or Cut Tape (CT), as these affect handling procedures. Ensure the part number matches the exact voltage and current ratings required for the target circuit design before procurement.

Single Diodes Selection Notes

Select this component when a 4A current rating and 400V blocking capability are required in a surface-mount form factor. Consider the thermal resistance of the TO-277 package for heat dissipation requirements in the final assembly layout.

Single Diodes Part Context

This device belongs to the TUAU_H series of surface-mount rectifier diodes from Taiwan Semiconductor. The series offers various voltage ratings while maintaining consistent current handling capabilities across different package options, providing designers with standardized solutions for power management applications.

Single Diodes Replacement Considerations

Check datasheets for equivalent parts offering identical 4A/400V specifications and compatible TO-277 pinouts. Verify that substitute components meet the same reverse recovery time and forward voltage drop requirements to ensure circuit compatibility.
