Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm package type and qualification status. Ensure the ordering part number matches the required voltage and current ratings for the target application. Confirm RoHS compliance and manufacturing origin details through authorized distributors or direct manufacturer channels prior to procurement.

Selection Notes

Select this component when designing circuits that demand both fast switching speeds and robustness against avalanche conditions. The TO-277A package offers a compact footprint with adequate thermal dissipation for 2 A continuous current. Consider the 175°C maximum junction temperature capability for high-temperature operational environments common in automotive systems.

Part Context

This component belongs to the AR4 series of fast recovery rectifiers from Vishay. The series includes variants with different voltage ratings such as AR4PD and AR4PJ. These devices are designed to replace bulkier through-hole alternatives in modern surface-mount designs while maintaining high performance and reliability standards.

Replacement Considerations

Publicly confirmed substitute part numbers include AR4PJHM3_A/H and AR4PKHM3_A/H. Verify pinout compatibility and ensure the replacement meets or exceeds the original voltage and current specifications before implementation.
