VS-80RIA40

Scrs Overview

The VS-80RIA40 is a silicon controlled rectifier (SCR) manufactured by Vishay General Semiconductor - Diodes Division. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state current capability of 125 A. The device utilizes a TO-209AC (TO-94) chassis mount package, suitable for high-power industrial applications. Key electrical characteristics include a maximum gate trigger current (IGT) of 200 mA and a holding current (IH) of 200 mA. The component is designed for robust performance in phase control and power conversion circuits.

Scrs Feature Summary

• High current handling capacity with 125 A on-state rating
• Robust chassis mounting design via TO-209AC package
• Standard recovery characteristics for reliable switching
• Defined gate trigger parameters for precise control

Scrs Applications

• Phase control applications in medium to high power systems
• Industrial power conversion circuits
• Motor speed control systems requiring high current
• Resistive load switching in heavy-duty equipment

Scrs Procurement Notes

Verify the specific suffix or variant against official Vishay documentation to ensure compatibility with required thermal and electrical specifications. Confirm that the TO-209AC package dimensions match the intended chassis mounting hardware. Check for any obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Scrs Selection Notes

Select this component when a 400 V blocking voltage and 125 A continuous current are required in a chassis-mount form factor. Ensure the application environment supports the thermal management needs of a TO-209AC package. Verify that the gate drive circuitry can supply the necessary 200 mA trigger current reliably under all operating conditions.

Scrs Part Context

This SCR belongs to Vishay's discrete diode and thyristor product line, targeting industrial and power electronics markets. The TO-209AC package provides a standardized mechanical interface for high-power modules. It complements other Vishay SCRs like the VS-40TPS12 and VS-50TPS12, offering higher current density for demanding phase control tasks.
