Procurement Notes

Verify the specific ordering suffix against official documentation to confirm lead-free status and packaging quantity. Standard production versions typically come in tubes of 50 pieces. Ensure the requested part number matches the exact electrical ratings and package style required for the design. Contact authorized personnel for written terms regarding specialized applications.

Selection Notes

Select this component when designing circuits requiring fast switching speeds and low conduction losses in the 400 V range. The TO-220AB package facilitates heatsink mounting for thermal management. Consider the thermal resistance values and allowable case temperatures when determining heat dissipation requirements for continuous operation at rated currents.

Part Context

This device belongs to the FRED Pt series of ultrafast recovery rectifiers manufactured by Vishay High Power Products. The series utilizes platinum doping to optimize the trade-off between forward voltage drop and reverse recovery time. It is distinct from standard or soft recovery diodes due to its specific application in high-efficiency power conversion stages.

Replacement Considerations

Check datasheets for alternative dual common-cathode ultrafast rectifiers with matching 400 V and 8 A per leg ratings. Verify that substitute components offer comparable reverse recovery times and thermal resistance values to ensure circuit performance stability.
