Diode Arrays Procurement Notes

Verify the specific suffix E3/81 against official Vishay documentation to confirm RoHS compliance and reel packaging specifications. Confirm availability status as distribution channels may list obsolete or end-of-life inventory. Ensure the D2PAK-2 footprint matches the target PCB design before procurement.

Diode Arrays Selection Notes

Select this component when a dual common cathode topology is required for 100 V systems. The 25 ns recovery time distinguishes it from standard rectifiers, making it appropriate for high-speed switching environments. Verify that the 10 A continuous current rating aligns with the thermal management capabilities of the final assembly.

Diode Arrays Part Context

This part belongs to the BYQ28E series of ultrafast rectifiers manufactured by Vishay Semiconductors. The series utilizes silicon epitaxial planar technology with glass passivation. The E3 suffix indicates lead-free construction compliant with RoHS directives, while the /81 suffix typically denotes tape-and-reel packaging for automated surface-mount assembly.

Diode Arrays Replacement Considerations

Cross-reference with BYQ28EB-100/81 for identical electrical performance in the same package. Verify pinout compatibility and thermal resistance values when substituting with other dual common cathode fast recovery diodes.
