Procurement Notes

Verify the specific ordering suffix to confirm the package style, as variants include standard leaded (D-61-8), surface mount (D-61-8-SM), and leadless (D-61-8-SL) options. Confirm that the requested part number aligns with the required mounting method and thermal interface specifications for the intended application design.

Selection Notes

Select this component for high-current applications requiring low conduction losses and fast switching speeds. Ensure the thermal management system can maintain the case temperature within limits defined by the 80 A rating. Verify that the 30 V reverse voltage rating provides adequate margin for the circuit's peak operating voltages.

Part Context

This device belongs to Vishay's New Generation 3 D-61 package series, designed for high-power density applications. The series utilizes advanced Schottky barrier technology to minimize forward voltage drop while maintaining robust performance under high thermal stress conditions common in industrial power electronics.

Replacement Considerations

Direct replacements must match the 80 A current rating, 30 V reverse voltage, and D-61 package footprint. Verify compatibility with existing thermal interfaces and mounting torque requirements when substituting with other dual Schottky modules.
