Procurement Notes

Verify the specific suffix against official documentation, as ordering codes may indicate variations in tape-and-reel specifications or manufacturing origin. Confirm that the requested quantity aligns with the manufacturer's standard reel size requirements. Ensure compatibility with automated pick-and-place equipment regarding the TO-277A-3 package dimensions. Cross-reference the part number with the latest datasheet revision to confirm material compliance and assembly site details before finalizing procurement orders.

Selection Notes

Select this component when a 4 A current rating and 200 V blocking voltage are required in a compact SMD footprint. The fast recovery characteristic makes it suitable for high-efficiency power supplies where switching losses must be minimized. The avalanche rating provides protection against voltage transients during turn-off, reducing the need for external snubber circuits. Consider the thermal performance of the TO-277A-3 package for heat dissipation in densely populated PCB layouts.

Part Context

This device belongs to the AR4P series of fast recovery rectifiers from Vishay. The series offers various voltage ratings and current capabilities within the same eSMP® package family, allowing for design flexibility. The AR4PD variant specifically targets the 200 V / 4 A segment, bridging the gap between lower current general-purpose diodes and higher power modules. It shares pinout compatibility with other devices in the SMPC package family.
