Procurement Notes
Verify the specific ordering suffix /87A against the manufacturer's latest datasheet to confirm reel packaging specifications. Ensure the procurement channel provides valid traceability documentation. Confirm that the component meets RoHS compliance requirements as stated in the official product specifications before finalizing orders.
Selection Notes
Select this component when a surface-mount solution is required for high-voltage applications demanding fast recovery characteristics. The TO-277A package offers a compact footprint suitable for automated placement. Consider the 175°C maximum junction temperature capability for environments requiring robust thermal performance compared to standard industrial grade alternatives.
Part Context
This rectifier belongs to Vishay's eSMP series, designed for surface mount technology. The AS3P family focuses on providing high current density in small packages. The TO-277A form factor allows for efficient heat dissipation while maintaining a low profile, making it suitable for space-constrained electronic designs requiring reliable rectification.
Replacement Considerations
Check for AS3PMHM3_A/H or AS3PMHM3/86A as potential variants within the same series. Verify pinout compatibility and electrical parameter equivalence before substitution. Consult the manufacturer's replacement guide for any obsolescence notices.
