VS-50RIA40M

Scrs Overview

The VS-50RIA40M is a medium power thyristor (SCR) manufactured by Vishay General Semiconductor. It features a 400V repetitive peak off-state voltage and an 80A on-state current rating. The device utilizes a TO-208AC stud mount package, designed for chassis mounting applications. It operates within a junction temperature range of -40°C to 125°C. This component is engineered for phase control and medium power conversion tasks requiring high voltage and current handling capabilities in industrial settings.

Scrs Feature Summary

• High current capacity with 80A on-state rating
• Robust thermal management via stud mount construction
• Designed for phase control applications

Scrs Applications

• Phase control circuits
• Medium power conversion systems
• Industrial motor drives

Scrs Procurement Notes

Verify the specific suffix 'M' against official Vishay documentation to confirm the exact electrical characteristics and mechanical dimensions, as variations may exist between standard and modified part numbers. Ensure the supplier provides valid traceability documents. Confirm that the TO-208AC package matches the required chassis mounting specifications for the target application before finalizing procurement orders.

Scrs Selection Notes

Select this component when designing circuits requiring a 400V blocking voltage and 80A continuous current handling. The TO-208AC package is suitable for high-power density designs where direct chassis mounting is preferred for thermal dissipation. Evaluate the gate trigger requirements and dv/dt ratings against the specific load conditions to ensure stable operation during switching events in phase control scenarios.

Scrs Part Context

This part belongs to Vishay's medium power thyristor series, specifically the RIA line. These devices are standardized for industrial use, offering reliable performance in harsh environments. The TO-208AC form factor is a legacy but widely accepted standard for high-current silicon controlled rectifiers, facilitating integration into existing equipment designs that utilize stud-mounted semiconductor solutions.

Scrs Replacement Considerations

Direct substitutes include the VS-50RIA60M for higher voltage requirements or other Vishay 50A/80A SCR families. Verify pinout compatibility and thermal resistance values when cross-referencing with competitors' equivalent parts to ensure seamless replacement without redesigning the heat sink interface.
