Procurement Notes
Verify the specific suffix /87A corresponds to the reel packaging configuration as defined in the official datasheet. Confirm RoHS compliance status through the manufacturer's documentation. Ensure the ordering quantity aligns with the factory pack size requirements specified by Vishay Semiconductors for this particular part number.
Selection Notes
Select this component when an 800 V blocking voltage and 3 A continuous current are required in a surface-mount form factor. The avalanche rating makes it suitable for applications experiencing inductive switching spikes. Compare thermal resistance values against system constraints to ensure adequate heat dissipation within the TO-277A-3 package limits.
Part Context
This device belongs to the AS3P series of rectifiers from Vishay. It represents a transition from traditional axial leads to surface-mount technology while maintaining high voltage ratings. The series is optimized for automotive and industrial environments requiring robust performance and space efficiency.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameters before considering any alternative components from other manufacturers.
