Procurement Notes

Verify the specific datasheet revision and RoHS compliance status before procurement, as manufacturing parameters may vary across production batches. Confirm that the ADD-A-PAK-5 pinout matches the target circuit layout requirements. Ensure thermal management solutions are adequate for the specified junction temperature limits during operation.

Selection Notes

Select this component for high-voltage rectification tasks requiring robust mechanical mounting via flange. The common anode configuration simplifies circuit topology for specific bridge or dual-diode arrangements. Evaluate the 800 V reverse voltage rating against system transients to ensure sufficient safety margins under all operating conditions.

Part Context

This part belongs to the Vishay IRK.71 and .91 series of thyristor/diode modules. These components utilize the ADD-A-PAK GEN V power module technology, designed for high surge capability and high voltage isolation. The series is characterized by thick copper baseplates and glass-passivated junctions for enhanced durability in demanding environments.
